Before we delve further into the AV observation it is important to understand the phenomenon of precision of equinoxes.

These years if you go out at night, looking at the north direction, you will probably be able to identify the pole star. If you sit for long and observe the pole star, you will notice that all stars revolve around the pole star. And, how do they revolve? In an anti-clockwise direction.

Now, what happens is this. We call it a pole star and we think it is steady. Dhruva Taara, where ‘Dhruva’ means fixed. It is fixed but it is fixed for maybe one thousand or two thousand years, it is not fixed forever. There is another astronomical phenomenon, where earth’s axis points to in the sky. If there is a star that we called as a Dhruva Tara, it has its own motion. It is a very slow motion like a ‘top’ that you play with and that is what we call ‘the precession of the axis.’ It’s very slow and it completes one circle in 26000 years.

We will start where earth’s axis is at an angle pointing towards the sky, NCP a star next to it. In our times, it is Polaris. But as explained, it goes and makes the circle. It has a precession around and it takes 26000 years.

So, let me ask you a question.  When would our earth axis point to that other star, Brahma rishi/ Abhijit? Thirteen thousand years either we go backward or forward, thirteen thousand years.


So we would go back to eleven thousand B.C, plus two thousand that is thirteen thousand years approximately. At this stage everything will be same except now, earth’s axis will be pointing towards Brahma rishi/Abhijit. What does that mean? Thirteen thousand years ago Brahma rishi/Abhijit was our pole star, not Polaris.

Now, what I am doing is, I am taking the same circle placing the position of some stars. And, now I want to place there, the relative positions of Arundhati and Vasishtha.




That’s how they are. Just for a demonstration, they are exaggerated and shown as wider. Now everyone understands if Polaris is my pole star they go around Polaris into an anti-clockwise direction.  I am going to draw a line that goes through Arundhati and Vasishtha and crosses that circle of precession twice.


Pay attention, that line has split that circle into 3 categories.

Point A, Point B and our current Point C and I am also going to mark down the Point X.  So, 5561 BC and that is my proposed date for the year of Mahabharata war.


It was not Nilesh but  Dr. P.V. Vartak, one of the four names already mentioned, who proposed it in 1980 sometime. So, as Nilesh says,”When I started working with it, my goal was to see if it is true; my goal was to actually disapprove that date.”

That line has split the circle into 3 different phenomena. The first one, that particular curve, we can say that the Vasishtha would appear walking ahead of Arundhati and let us see, why? When that line cuts that circle at two points A and B, 4508 BC. Those two points, let me ask you a question.

When that line cuts that circle at two points A and B, 4508 BC. Those two points, let me ask you a question.

Where do you see the pole along that curve and line, who would appear ahead and who would appear behind? Think of it as a clock and that line is the arm of the clock. Arundhati and Vasishtha are on that arm. Anyone ahead or anyone behind? They will be coinciding. Arundhati and Vashishtha will be together. No one is ahead no one behind in those two years.

And, the last one. Anytime, when the point of the North Celestial Pole is along that green area. You will see that Arundhati would appear walking ahead of Vasishtha.

In today’s scenario. So just for the reference and for help, we are drawing those trajectories for each of those stars. Just by looking at pictures, everyone will agree that here, Vasishtha would be walking ahead of Arundhati. let’s look at the simulation.

And, now let us look at the simulation.

If you look at the astronomy simulation that vertical green line think of that as a 12’o clock in your clock. It’s the meridian in the astronomy. Vasishtha has already gone ahead crossed the meridian, Arundhati is behind. We may check the year and it is 2016, our times.

So, now I am going to look into these points A and B. When the North Pole, the point of North Pole was at A and B, that was in 4508 B.C and also 11091 B.C.

From B now, let us draw those arms again, they are aligned with each other. And, what do we see? We will see Arundhati and Vasishtha walk together. Let’s do the simulation. At the meridian both crossing together, no one ahead no one behind.


In order to be clear, the place of Dhruva Tara is the point A or B and Vasishtha and Arundhati are walking around A or B and all other stars of that area too.

Let’s do that for 4508 BC. Again I am doing from point A.  Let’s look at simulation for that year, again the same thing no one ahead, no one behind.

Let’s look at the last scenario. So, now I am deliberately keeping that red line as reference line because you know that no one is ahead and no one is behind. And now I am going to draw a line from this point of North Pole in 5561 BC to Arundhati and Vasishtha. And, what

What can you say? Not much difference! But what do you say if they are moving in anti-clockwise, you will see Arundhati walk ahead of Vasishtha.

But what do you say if they are moving in anti-clockwise?  You will see Arundhati walk ahead of Vasishtha.


And let’s look at simulation. It is important to notice that there is not much difference and they are going anticlockwise but Arundhati had already crossed the meridian. Vasishtha yet had to cross the meridian and that was the scenario. That was what was happening from 11091 BC until 4508 BC, until 6500 years ago.

So now back to the triangle of science if you want to bring this all together, what will we do? We do the testing and see the empirical proof. So that anyone of you should able to go back and test it. You do not have to trust me on this. So, we start with the explanation, what is the explanation? Simple! Arundhati is ahead of Vasishtha. The testing or the question is, is it even possible? Those people who thought it is not possible, they said somebody had inserted it. But when somebody finally proved, actually showed that it is possible, the question is, when was it possible and when was this the case? And the answer is some time from 11091 BC until 4508 BC, around 6500 years. Anytime anyone on the earth in northern hemisphere looking at Arundhati and Vashistha during this time would have seen Arundhati walked ahead of Vasishtha.

So, now we bring all of this together and let us adorn our scientific hats. We have got our empirical proof, we have got the “Shabda Pramaan”, somebody’s claims . Arundhati walking ahead of Vasishtha, we got empirical proof? Yes, that indeed it went ahead of the Vasishtha. If you combine the two, we should be able to assert that Mahabharata war did not happen any time after 4500 BC.

This one single observation. Bring back the example that we have dealt already of Lokmanya Tilak in 1920. It doesn’t matter whether it said 23 or 31 or 37, doesn’t matter. Similarly any year of Mahabharata war that falls after 4508 B.C, this one observation says, it is wrong.

Now I want you to bring that skeptic in you, what will you say?  “Okay. That’s fine ‘Shabda Pramaan’ matches with the ‘Pratyaksha Pramaan’, empirical proof that’s all nice but come on, that is just one observation.” Could this be a random coincidence? It’s possible.When we talk about science we are talking about more likely and less likely and there is no certainty in science.  It is very humble, it is also very fearless. It feels comfortable making claims and it encourages others and says come and prove me wrong, that is science.

So, somebody says that is a coincidence; it may be one reference and not all. Remember! There are 215 and you can go just one after another.

Let us look at a quick summary of another one.

Deductive reasoning based on Bhishma Nirvana.

It is just like what we just saw in AB observation. It’s totally different from it, nothing to confuse with the AB observation. We can also prove with the same force that Mahabharata war, just based on 23 references of Bhishma Nirvana, did not happen a day late than 4700 BC or before 7000 BC.

So again this set of observation also instantly falsifies any date that falls after 4500 BC.

And what will the skeptic the say? He would say,”Alright! But these are only the two sets of observations. Could these be random coincidences?” But no we have many others, you can just go through seasons and go on and on.

I would encourage the readers to read the book written by Nilesh Nilkanth Oak or even his blog. There are around 400 blogs that he has written, essentially responding to the questions like these.

My people uprooted

8 April 1950 a fateful pact signed betn Jawaharlal Nehru & Liaquat Ali Khan,PM of Pakistan. After 2 months of Govt-engineered pogrom,slaughter, rape of Hindus in East Pakistan. Estimated 50,000 Hindus killed. An instance of incredible political stupidity on Nehru’s part.

Upon Liaquat’s glib assurance that Hindu refugees would be taken back and restored,the gullible Nehru decided that no rehabilitation of Hindus was necessary in India. Result: no refugee went back and were forced to live under inhuman conditions in Indian camps.

The Pakis were so insincere about the pact that their Govt issued secret instructions not to restore any Hindu to his property. Even after the pact all Hindu passengers in down Assam Mail were pulled down and killed just outside Santahar station.
