A Short Discussion on Story Transition (Parivartan – in Hindi)

At Indiansciencefiction.groups.yahoo.com in 2009 by some Sci-Fi giants

Dr. Arvind Mishra

Friends,

Zeashan is my favourite sf writer who writes stories in Hindi.I just saw this story Parivartan (Transition) by him and thought you would also enjoy reading it ! But I am recommending this story with a purpose -to suggest an alternative end of the story as its drop scene was not somehow liked by me .I have suggested the author also to explore other poossible ends to the story and if possible rewrite it or write a sequel of it.

Would you be kind enough please to help the writer?

Hello,

An unexpected twist at the end! Didn't see that coming at all... The

story brought a smile to me... Heh... Just need to know this, if

D'souza was indeed a robot, why did his makers have to make him

anatomically complete.... Unless he was intended to serve the purpose

that he was being put to by the protagonist' s wife. Ahem...

:) I think we need a backstory to the story... Cause that bit is

unexplained. ..

Weirdly I found the story funny... What that the intention?

Cheers Zeashan!

Cyril

Dr. Arvind Mishra

D'souza was not a robot but an Android-a humanoid in all respect !

Ending was the reason I loved the story. Rest of it was rather mundane,

but ending made my day when I saw part 2 yesterday night.

Dr. Arvind Mishra

One more thing about Zeashan ' s story -its a diversion from typical Asimovian robotics premise ! Not just one but two humans have been shown to get murdered by a robot ? Is it Ok with you all ? It was the reason why I was a bit uncomfortable with the end ? Any caveat for/from Zeashan's side?

Cyril Gupta

I don't the Asimovian rules should be considered Universal. The three

laws of Robotics, and also the zero'th law were invented by Asimov so

that he could concoct his stories around them. In other science

stories there can be assassin robots, so the laws don't have to hold,

not on everybody.

I really don't think that Zeashan's story has a problem because it

violates the Asimov's robotics laws. Just that a lot of the backstory

is missing so there's a certain amount of abruptness, but surely if

there was backstory then the ending would become expected and the

surprise will be ruined.

It seems that in Zeashan's story, the robots are first-class citizens

of the society (judging from the way the protagonist treats them early

on, and then at the end). They're sentient and have similar urges and

emotions to a human being.

Tinkoo Valia

There are far too many stories of killer robots out there - most often

as war machines.

And have you seen Jack Williamson's "With Folded Hands"? Even robots

governed by "benign" laws can do far too much damage to people around.

Unfortunately, this widely read classic doesn't seem to be online.

Asimov's Three Laws are only one of the many robot behavior premises

examined in fiction.

PS: Incidentally, Asimov tells us in one of his anthologies that his

robot stories began with ideas from Eando Binder's "I, Robot". And

Binder tells us his story is a reaction to Mary Shelly's "Frankenstein"

- that man's man-like creations need not be bad! Comic book version of

Binder's classic is online:

Cyril Gupta

Has anyone read Ray Bradbury's Marionette's Inc? That's another story

in which a married couple deceives each other using Robots, and though

the man doesn't get killed, he does witness a Robot who falls in love

with his wife...

As for killer robots, there can be nothing beyond the Berserkers who

are Death incarnate, and of course if you read pulp science fiction

then you can think of Daleks, and the Cybermen of Dr. WHO.

So I guess there's enough precedent for Zeashan's story that it

doesn't seem at odds to the established scientific norms, and even if

it were I think we should welcome it, because any new perspective on

science and its impact should be entertained. :)

Dr. Arvind Mishra

So congrats Zeashan ! your story get across well in a rogourous peer review! You come out with flying colours ! Thats graet...keep it up !

‘Electric Rioters’ Explained.

A reply by a SciFi fan Ms. Reema Sarwal on the questions raised by Mr. Swapnil Bhartiya on my story ‘Electric Rioters’. (See the previous post)

Swapnil ji,

I was completely flabbergasted by your point nos. 3 and 4 !

>>"The movement itself will raise suspicion among authorities."

I'm amazed at your utopic faith in the authorities! ! They notice NOTHING. I repeat, nothing. They wouldn't notice if you transported a rocket from Point A in the Himalayas to Point B in Tamil Nadu via road.

We're talking "authorities" who don't see entire colonies being built on ground surface in the capital city of Delhi. What chance do they have, given a millennium, of having a single clue about an underground laboratory being built below a Tribal temple in the heart of a jungle? Whatever made you dream of such a thing as land acquisition in this case?

I'm also not sure what makes you talk of a "factory" -- I read it as a fairly usual lab, though advanced, with some computers, 2 human-sized glass capsules, 2 beds, medical equipment, and some laser machinery -- pretty much humdrum for SF. Besides, our scientist is employed at a high position in the government, he could easily steal most of the stuff he needed from his official lab and contacts -- that's something we obviously expect of him! He's surely not a "normal" govt. employee if he can't even do that much.

As for point no. 4, to protect urban "citizens" from "uncivilized" tribals, the orders would be loud and clear -- shoot to kill. I particularly liked the satire at the beginning of the story when one cop suggests that the entire tribal community should be exterminated. That's one of the reasons I said it was a good story-- it captures the attitudes and mindset of our society.

What was Unexplained in ‘Electric Rioters’ ?

Mr. Swapnil Bhartiya, a reviewer and chief editor of Sci-Fi online magazine kalkion.com raised some questions on my story ‘Electric Rioters’

Hi Zeashan!

As I said earlier good story, that too when delivered on Demand model. I found certain points unexplained.

1. As Reema ji said, a scientist has a completely different mindset. He/she is not a planner/schemer -- rather sometimes he/she may not even know what to do with his creation. Its the corporation, which tries to find a purpose of that creation. It would be better if an evil corporate with whatso ever purpose deploy a scientist to achieve something.

2. There was no apparent reason for which he would want to destroy people. What would he achieve?

3. Setting up such a huge factory would need state-of-the- art infrastructure, talent, man-power, land acquising, transporation of equipment, import/production of such equipments, and then HUGE funding. The movement itself will raise suspicion among authorities. So, as per logic this is not feasible.

4. Why only dead Tribals? If you shoot in leg, then also you can capture someone?

5. Why machine gun? Why would he need a machine gun? He did not need any defense? Also if he did then a pistol will do?

6. It was even better to kill them through electric man instead of a gun?

These are some points :-)

It was fun reading it, otherwise.

Sci-Fi Story on Demand

The story ‘Electric Rioters’ which you read before, I wrote in Hindi on the demand and concept of a SciFi fan Reema Sarwal. She raised a question whether a human can be electrified?

After completing the story I received some valuable comments on my story :

Reema Sarwal’ Comment :

Zeashan ji, Thank you for writing this story on demand !! As usual, it shows your excellent command over an intriguing setting and a racy plot that makes for an interesting read !

Um, isn't it strange that the scientist should be so careless as to be electrocuted by his own slave? But more importantly, history proves that scientists, however mad, never wish to rule the world - that's not at all what they want from life - they're happier doing more research! And in this story, there is no revenge motive either (for the scientist) to make it sound probable, nor is he doing it for some other controlling organization.

The story also makes me feel very sad because the scientist cannot think of any productive use for his invention and such a good invention too, which could have been so good for the tribe in many other ways than saving them from the outsiders, and it is then lost to the whole world !

That said, it is still a pretty good story as it addresses the all-important issue of preserving natural habitats in such a unique fashion.

Thanks again!

Dr. Arvind Mishra’s Comment :

I must admit that I have an inherent inability to be non judgemental whether a particular story is good or bad .Reema has indeed raised certain logical points which I trust shall be suitably addressed by the writer-but one thing which I appreciate is the writer's ability to accept the challenge to write a story on a given theme and Zeashan has not dissappointed us. In Hindi pulp novels there has been a stereotype of a mad scientist desirous of ruling the world and Zeashan has just followed the trend –

but I APPRECIATE Reema's outlook also which portrays a scientist as an angel ! ( Being one myself ! ha ha ! ) .Thanks Reema for having such a nice attitude towards scientists !

The pitfalls apart I like the Zeashan's specific style the way he makes the plot to have an errie environment reminding me of the famous Tilism stories of CHANDRKANTAA SANTATI. 

The Farthest Star is the Nearest Star

---Zeashan Zaidi

According to maths, the distance between the two points depends on the path which connects the points. For example, let A and B are the two cities. And there are three ways which connects A and B. The first way is hundred kilometers long while the second and third are sixty kilometers and eighty kilometers long respectively. So according to the first way the distance between A and B is hundred kilometers, while this distance is sixty kilometers and eighty kilometers respectively along with the second and third paths respectively. This rule is applicable to the entire universe. So it is clear that a thing could be near as well as far away from us at the same time.

Let us take another example. As we know that the earth is round. Let there are two cities within a country. If we make two routes between cities, one within the country and other around the earth, going in the opposite direction from one city to other; then first distance will be small while the other large. And thus the distance between the two cities at the same time will be too small and too large. As well as 'small' distance will be smaller, 'large' would be much larger. This is possible due to the roundedness of the earth. This distance also depends on the surface on which it is measured relatively.

Now let's talk about a branch of mathematics called Calculus of Variations. It was developed in the early 18th century by the famous mathematicians Leonhard Euler and Lagrange. This mathematics measures extreme values of heights, distances, time or energy etc.

So using calculus of variations we can find the minimum or maximum condition of something. But one drawback is that if we find maxima then we generally can’t find the minima or vice versa. In many cases we get only one extreme value (maxima or minima) and the second value comes either infinity or negative infinity.

But if we take the above assumption that as 'small' distance will be smaller, 'large' would be much larger we can say that the minima found will also be the maxima or vice versa.

For a closed surface (such as rounded ground) Maximum - Minimum be together is perfectly clear.

Now look at the second situation. Let we are interested in minimal distance between the two points. The distance between the points depends on the surface on which the points lie. If surface would be change, the minima will also change. The same shall also apply to the maximum. In this way we see that the distance between two locations in different situation will maximum and minimum in many ways.

This rule is applicable for not only the distance but also time, energy and other physical quantities.

So a star we see very far away, can be extremely near to us perhaps after changing the surface of space. Is this concept is similar to the concept of wormholes? 

Before the Big Bang the universe was contracted?

The big bang theory says the early universe was made up of hot plasma of photons, electrons and baryons. The photons were constantly interacting with the plasma through Thomson scattering. As the universe expanded, adiabatic cooling caused the plasma to cool until it became favorable for electrons to combine with protons and form hydrogen atoms. 

The question is how that hot plasma formed? Like today’s process there was some process which were converting photons, electrons and baryons into the hot plasma. Perhaps it was a contracting process converse to adiabatic cooling.

As in the present universe, expansion causes the cooling. What will happen when universe will become too cold? Its answer is depending upon the current density of universe. The problem with measuring the current density of our Universe is that we cannot see most of the matter in it (The dark Matter). 

If the universe is heavier than the critical point, it will result in a shrinking universe. Though probability of this situation is only one third, but combining with the big bang it becomes more probable. 

Universe Will Contract After Expansion.

In the whole universe, everywhere we see two types of processes. Either expansion or contraction. Let we first take example of living organisms. They first grow up (expand) then rotten (contract). If you see a rotten fruit using speed photography, it contracts and emits gases and other elements (expansion). Sometime rotten and putrid things bloat (expand) instead of contracting; and many living things become smaller as they grow. Insect Larvae are a prime example. 

At macro level, stars after its birth expand. Once the hydrogen fuel at the core is exhausted, a star of at least 0.4 times the mass of the Sun expands to become a red giant. This is the process of expansion and then sometime ends on black holes; a process of contraction, though most stars in the universe end up as white dwarves which ultimately become brown dwarves. All these are the examples of expansion – contraction.

Stars that begin with more than 50 solar masses can lose over half their total mass while they remain on the main sequence. This is process of contraction in term of mass.

Stars of at least 0.4 solar masses exhaust their supply of hydrogen at their core, their outer layers expand and cool to form a red giant. It is expansion in terms of volume.

In a red giant of up to 2.25 solar masses, hydrogen fusion proceeds in a shell-layer surrounding the core. Eventually the core is compressed enough to start helium fusion, and the star now gradually shrinks in radius and increases its surface temperature, which is a process of contraction.

In this way we can form an hypothesis that our universe will contract after the current process of expansion. And then again it will be converted into a small point as it was in beginning before the big bang. 

Existence of Continuous Particles.

As we know, we all and this world are made up of two fundamental particles Fermions and Bosons.

Fermions form matter. Its examples are electrons, protons etc. Similarly those particles which create forces are known as Bosons. They are not matter particles and include particles like photons and gluons.

And all these particles are discrete; so we can study these particles through quantum physics.

Now a question arises. Does any particle exist; which is continuous in nature? Means a particle which does not has individual existence but it is real within a certain period; same as in mathematics, a single point is just an abstract concept but the continuous group of points makes real object.

A time particle may be an example of such type of particles. A time-particle alone has no existence but within a certain period its existence detects.

But there is a problem if such particles exist. We can experimentally verify a thing which is discrete and split-able in nature. We see an element in lab because it is made up of atoms and some atoms can be collected in lab. But if element was not made up of discrete atoms, we could never detect it into any lab. Therefore any lab and experiment capable only for seeing discrete things couldn't see continuous particles.

---Zeashan Zaidi    

We do not exist.

Just for fun.

I am trying to prove our non existence.

1. We are matter.

2. Matter exists in the space.

3. Space is the set of locations that are marked by points.

4. Point is dimensionless and so the locations.

5. So the set of locations i.e. space is also dimensionless.

6. But matter does not exist without dimensions.

7. So we do not exist.

???    

Is universe an intelligent entity?

As we know atoms and molecules do not have intelligence. But their bigger groups i.e. cells and living bodies have intelligence to some extent. We are intelligent entities made up from unintelligent atoms and molecules and we have unintelligent components water, minerals and protein molecules. 

Now a question of interest arises from this fact: Is universe an intelligent entity made up of unintelligent components like galaxies and stars?   

Is it worth to Search Science in Mythology?

My friend Swapnil Bhartiya reply:

There is no point in debating Mythological issues. Trying to find science behind it is like beating the bush, we need to move on. Even American magazines have clearly said they don't want stories re-searching facts behind Biblical stories. Imagination is a human capacity and whether its Hanuman flying or Pushpak Viman, they are just the imagination of people of those times and there is no need to call the Lord Indian Superman or see facts behind him.

While I am aware scientists are trying to find the secret behind Sanjeevni booti (I read a news article), or relics of Dwarka, but that is for scientists with equipments, we writers are not properly equipped or have resources to peel down -- if we try that would be injustice.   

It can be the Plot of a Sci-Fi Novel

Last night I saw a dream.

That I am a superhero who can fly everywhere at any speed. My cunning friend is a great scientist. He invented three things. An intelligent robot, a box like jail which neither a person nor any weapon can penetrate; and third is a needle like missile which never abandon its target without destroying it. I and my friend love to same beautiful girl. This is the beginning of dispute but at the moment, It is founded some problems in robot’s circuitry and he also drown in love to same girl. 

And now we are the two enemies for him. Therefore he throws tow needle missiles for killing his enemies. Now my scientist friend is hidden in the self invented jail while I am flying with top speed to defend myself to the needle missile.

What will happen next?   

Can we make dream machines for future predictions?

--Zeashan Zaidi

We all see dreams. Mostly are not real and we forget after waking up. But there are many examples in history in which someone saw a dream and then his dream appeared later into a real event. One famous example is the President Abraham Lincoln’s murder. President Abraham Lincoln first saw a dream about his murder which unluckily came into reality after a short time span.

Now the question, ‘Is there any physical theory behind seeing the real dreams?’ Can M-theory or some other theory explain these things? It might be possible that an event happens into our dimensions may already be happen previously in some broader dimensions. And we see the shadow of that event as dream. If it is true then we can make almost accurate forecasting by making some dream machines. 

Fantasy towards Science

Indian Sci-Fi writer Dr. Arvind Mishra view on science fiction :

Let we discuss the very hybrid nature of SF –the marriage of science and fantasy, the unison of seemingly two opposite humane attributes.  But how to define SF academically? I am too little an authority to attempt doing such an academic exercise but there seems no harm in making at least a try? Isn't it? We are already familiar with many literary forms of social fictions i.e. stories, novels, novelettes etc, which depict several shades of our society in a lucid and interesting manner. 

The themes and plots of such social fictions are based only on past or present happenings related to man and his society. That is why the oft repeated adage, "literature is the mirror of society". Science fiction on other hand is the portrayal of man's future. And here lies the difference between social and science fictions, notwithstanding the many similarities of both the genres as they entail identical ways of storytelling, selection of a theme and structuring a plot around it and above all engaging the readers with a continuous and sustained flow of suspense leading ultimately to the climax of the story. 

But the million dollar question still remains unanswered, “how to honour this genre by giving it a proper and intelligible academic definition"?

Past was Mythology, Future is Science

It is an accepted fact that mythology has a lot of imaginations which are not possible scientifically. But I think almost every concept which is presently a myth would be a real story of future. In this context we can take example of Arabian Nights, the tales of 1000 nights which contains a lot of fantasies, many of them are the challenges of our modern S& T. That is;

One will say ‘Khul Ja Sim Sim’ and the door will open.

One will say ‘Chhoo Mantar’ and he will disappear.

A light will emit from your sword and the enemy roaring on you will changed into a cat.

A person will rub a ‘lamp’ and the Jinn will appear.

The S & T is now approaching to convert such imaginations into reality. For example the voice recognition technique, in future can control a door which would be open only on saying some code-words. Similarly science can make a special ‘mantra’ which is associated with the visibility – invisibility of someone. The making of invisible man is possible with futuristic optical techniques. Why extremes of biotech can’t convert a woman into a cat? Those miraculous phenomenons are possible with interconnection and advancement of various branches of S&T.

In future, a ‘Jinn’ can appear by structured combination of LASER and some other powerful rays emitted through a ‘lamp’ type transmitter. 

Is soul a special form of energy?

This is an interesting question for sci-fi writers as well. One of my friends scientist Dr. Chandra Mohan Nautiyal views on this topic :

Concept often Soul is not supposed to be material.  So it can't have mass.  The difficulty is that science is not so advanced as to be able to answers all questions.  We still don't know why matter should have gravitational property.  If there are positive- negative charges, North- South poles, then why don't we have opposite gravity i.e. attractive and repulsive variants of gravity?  Is quark the ultimate unit of matter?  Can there be gravity without mass?  Neutron may be electrically neutral over all but what about internal distribution?  It has magnetic moment after all!  Electrical and magnetic fields act at a distance and have electro-magnetic waves.  Are their gravitational waves?  If not, how does one body detects another and attracts?  Is and why is gravity inherent to mass?

Photon can behave as waves as well as particle (the famous wave- particle duality). Photon has zero (rest mass) i.e. when still, its mass is zero.  It has no charge hence free from Columbic interaction.  As particle, photons can be scattered.  This means that it changes its direction (exchanges energy/ momentum) on collision.

Soul doesn't have a shape or figure. For reflection, deflection, scattering, there has to be a field or matter to cause them. The position of mass may be different from position of the field.  It's like this:  a magnet on a table may have a magnetic field above the table. 

For magnetic field we require a magnet, for electric field we need charge (e.g. electrons, which have mass), or for gravitational field, mass .  We see an object if our eyes receive photons from that object.  The photons may be generated in the object or scattered/ reflected by the object.  Theoretically, energy source can lose energy as photons.

Are Virtual and Real worlds the two faces of a single coin?

‘This world is just an illusion’ like sentences might be true statements under some scientific point of views. Many of the times we see something at some place, actually which is not at that place. A star visible to me at a particular place in the sky is a real thing in our vision, but actually we are looking at a very old star which has presently changed its position as well as the shape. Heisenberg uncertainty principle implies that we always see illusions.

Now from another point of view, we are the species of four dimensions. The lower dimensional things such as shade, point, circle are all the virtual things for us. So it is possible that we are the virtual species for some higher dimensional living beings.

We see a world in our night dreams and after waking up we realize that the world we were seeing was only an illusion. In the same manner, can’t we say that today’s real world is actually virtual, which we will realize after waking up from a long sleep (death)?

We think that our body, our relatives etc are same since our birth and childhood. But it is also an illusion. Our body completely changes in span of one month. The old cells of the body die and new are born. So every month we take a birth.

So can’t we say that every reality is really virtual?  

Sci-Fi of Events (A thought)

I think that any creativity made by human always exists in nature. It is only the presentation by which we say that it is a new creation. So if a person creates something new, it is a new version of some old creations made by nature or human itself.

Einstein principle of conservation of mass and energy in the universe is also applicable for events of universe. Event neither be created nor destroyed, it only changes shape in different parts of universe(s). Therefore there is no past event, no future event. Event which is past for we, might be a future for some other place (or Universe). 

Because time has different speeds in different universes, it might be negative with association to some negative universe where all physical laws behave opposite relative to our universe and perhaps the past time of there will be the future time of here.

Will the Human be Able to Create His Own Micro Body within 20 years?

When I raised the said question after finishing my story “UnderEstimate”, famous Sci-Fi writer Dr. Arvind Dubey (Lucknow, India) said :

Not twenty years from now, its in front of u . Pof Yamanaka from Quoto university in Japan has done it. He introduced four transcription factors in a normal cell of adult mice to convert it into an adult pleuripotant cell, I mean a cell which can create a whole animal. What are these adult pleuripotant cells, of course a micro body. If y any means it can be transported to longer distances, Zeashan’s prophecy turns into a reality. However his perception of micro body is different from this, so what, Jules Verne was also having a different perception for the voyage to the moon, which later turned into the reality later on. Well done Zeashan, congratulations.

Here is the original news

Shinya Yamanaka Reprograms Human Adult Cells

Into Embryonic-like Stem Cells

Breakthrough accelerates new avenues of stem cell research

SAN FRANCISCO, CA – November 20, 2007 – Acclaimed stem cell researcher Shinya Yamanaka, MD, PhD, has reported that he and his Kyoto University colleagues have successfully reprogrammed human adult cells to function like pluripotent embryonic stem cells. Because it circumvents much of the controversy and restrictions regarding generation of embryonic stem cells from human embryos, this breakthrough, reported in the journal Cell, should accelerate the pace of stem cell research.

Last year, Yamanaka, who is also a senior investigator at the Gladstone Institute of Cardiovascular Disease (GICD), reported that he and his Kyoto colleagues had reprogrammed mouse skin cells into pluripotent stem cells, laying the foundation to apply this methodology in human cells.

In this earlier work, published in Cell, Yamanaka and his colleagues identified four genetic factors that resulted in the reprogramming of adult mouse cells into induced pluripotent stem (iPS) cells capable of developing into any kind of cell. This summer, he reported in Nature that these iPS cells could even form a new mouse, making them functionally the same as embyonic stem cells. According to the new research, those same genetic factors used with human adult cells resulted in iPS cells which are nearly indistinguishable from human embryonic stem cells.

“The rapid application of this approach to human cells has dramatically changed the landscape of stem cell science,” said GICD Director Deepak Srivastava, MD. “Dr. Yamanaka's work is monumental in its importance to the field of stem cell science and its potential impact on our ability to accelerate the benefits of this technology to the bedside. Not only does this discovery enable more research, it offers a new pathway to apply the benefits of stem cells to human disease.”

“Dr. Yamanaka and his group have made yet another extremely important contribution to the stem cell field,” said Richard Murphy, interim president of the California Institute for Regenerative Medicine (CIRM). “Their results open the door to generating alternative sources of pluripotent cells from patients, which is a major step forward. However, much work still needs to be done to fully characterize and understand the capacity of these induced pluripotent cells to study and to treat human diseases.”

While Yamanaka's work would seem to eliminate the need for controversial research on human embryos, both he and Srivastava emphasized that research must continue. “We are still a long way from finding cures or therapies from stem cells and we don’t know what processes will be effective,” Yamanaka said.

CIRM's Murphy added, “Dr. Yamanaka's work, which uses viral vectors to introduce into cells pluripotency- associated genes, further emphasizes the critical need we have to continue working with naturally occurring human embryonic stem cells, which remain the gold standard against which all alternative sources of human pluripotent stem cells must be tested.”

According to Yamanaka, the next steps will be to understand how these cells can be differentiated into other types of cells and ultimately how they can be used to study disease models and as potential therapies. “We are now finally in a position to make patient-specific stem cells for therapies without fear of immune-rejection and to make disease-specific stem cells that will reveal the underlying cause of many human diseases” he said.

Under Estimate - A short Review

A short review on my story 'Under Estimate' by SciFi writer Dr. Arvind Mishra

The above captioned science fantasy of Zeashan is an attempt to rationalize whether a man could leave its body and travel beyond in its 'energy' form ? Such descriptions could be found in many of our scriptures where sages have been shown to possess this amazing power of leaving temporarily their bodies as and when required to meet some noble causes and then return /enter back to/into their original bodies.

They have also been shown to even occupy some other vacant [dead] bodies when such needs arise. Termed as 'Parkayaa Pravesh'[entering the other body] this phenomenon of our folklores have fascinated us since long.

Now here is a science fantasy on it ! A daring task accepted and successfully carried out by Zeashan.
