Astronomy observation of Bhagavad Gita

A reader of ‘The Historic Rama’ wrote me an email two days ago and called me this morning. He knows Bhagavad Gita by heart. He was calling me to express his excitement after reading ‘The Historic Rama’.

However the reason he called me was to ask me to research on something very important he had found in Bhagavad Gita. We had a long discussion, but I will get to the point.

He told me that in Bhagavad Gita – Vibhuti Yoga, Krishna states that the divine can be perceived in the month of Margashirsha and also in the season of Vasanta (spring).

He was fascinated by my work on Archeo-astronomy and wanted me to ‘prove’ that lunar month of Margashirsha and season of Vasanta (spring) coincided at the time of composition of Bhagavad Gita (and thus Mahabharata War).

I thanked him for his enthusiasm. I also told him that I am aware of the Bhagavad Gita reference he was quoting and that I had analyzed it as early as 2009 CE.

However he was in shock (I don’t know why) when I told him that it is more likely that Krishna refers to lunar month of Margashirsha, in the Vibhuti Yoga (Adhyaya 10 of Bhagavad Gita) very much because the month (Margashirsha) coincided with the season of Sharad (pre-autumn) at the time of composition of Bhagavad Gita (and thus the Mahabharata).

Let’s look at the original Shlok:

Bhagavad Gita 10:35

बृहत्साम तथा साम्नां गायत्री छंदसामहम
मासानां मार्गशीर्षोsहमृतूनां कुसुमाकर:

The above Shlok from Bhagavad Gita (and thus Mahabharata, Bhishma Parva) has two astronomy observations. The fact that they are astronomy observations is not at all obvious. In addition, it is indeed challenging to interpret them without taking into account rest of astronomy observations of Mahabharata.

The point of spring equinox coincided with nakshatra Mrigashirsha during 4460 BCE. This meant the lunar month of Margashirsha was the median month of the Sharad season during 4460 BCE.

The correspondence between lunar month of Margashirsha with that of Sharad season (beginning, middle or the end) would span from 4460 BCE +/- 2000 years, i.e. 6460 BCE – 2460 BCE.

I have shown the year of Mahabharata War to be that of 5561 BCE, which indeed falls in this interval (6460 BCE – 2460 BCE).


And what about the claim that Krishna also refers to season of Vasanta (spring) in this same Adhyaya?

Not just same Adhyaya but rather in this same Shlok, Krishna refers to season (Rutu) of flowers (Kusumakar). And while it is true that both seasons – season of Vasanta (spring) and season of Sharad (pre-autumn) are seasons of flowers, the appropriate meaning here is to interpret ‘Kusumakar –Rutu’ as referring to season of Sharad.


I am aware that those who put all their faith in an ’authority’ (of their choice – of course) may not immediately digest the above fact, i.e. Lunar month of Margashirsha coincided with the season of Sharad (pre-autumn) during the time of Mahabharata War (and thus the time of composition of Bhagavad Gita).

However, Archeo-astronomy comes to our rescue again. Anyone, who has trouble internalizing above interpretation of mine (Lunar month of Margashirsha and season of Sharad) may want to ponder on the following:

If one insist on lunar month of Margashirsha coinciding with the season of Vasanta (spring) at the time of composition of Bhagavad Gita (and thus the Mahabharata), this would mean The Mahabharata War took place sometime during….

(Inhale deeply. Hold your breath, Exhale slowly. Relax.)

16400 BCE +/- 2000 years (18400 BCE – 14400 BCE)!

Any takers?
BTW, the above gentleman has promised to get back to me within a week.
