The Rig vedas stand as a proof of immense antiquity of Hindu / Vedic culture in this Karma bhoomi of ours. Unfortunately its antiquity has been undermined for long. The link to the reaserch document by Sri Narahari Achar is given below. This provides authentication that some of the available Rig vedic hyms date as far back 7000 BCE.
In this context we must recall some facts about the Vedic past.
The Vedas are as old as mankind itself. They have been conceived everytime human race (manvanthra) has revived itself. The currently avilable hymns were just four of thousands of Vedas that existed until Mahabharatha times. By the time of Mahabharatha, most of them have lost relevance to the changing Dharma- cycle of Kaliyuga. It was krishna Dwaipayana, popularly known as Ved Vyas who, with his foresightful wisdom made a selective choice of hymns from the then available mass of Vedic wealth, that can be useful and applicable in Kaliyuga.
What we have today as the 4 Vedas are a compilation of hymns from different sources (rishis) given at different periods in the past.
As such, there is no particular chronology of the vedas. They have been evolved simultaneously at all times. The 4 vedas thermselves were not evolved in any chronological sequence. Their contents only have been serialised as 4 vedas. But their origin had happened at all times simultaneously in the past. By this it means that a rig vedic hymn could have been evolved at a period later than a dated Atharvan hymn while there may be another Rig Vedic hymn evolved 1000s of years before that. There is absolutely no gradation in the period they have evolved. The gradation is with reference to the serialisation which Vyas had done.
Sri Narahari Achar has brought into focus the hymns that evolved as early as 7000 BCE! The Vernal equinox was at the comemncement of Bhadrapada (at present it is in Piseces / Phalguni). Rama's birth happened when the vernal equinox was at the commencement of Cancer! Krishna's birth was at the time of vernal equinox at the commencement of Taurus. The grand divison of Time as yugas is applicable in keepng time such as this!
Rama's birth time can be established on the basis of many corroborative evidence. The planetary software has been used by scholars like Prof Vartak and Prof Bhatnagar to place the date at 7000 years ago from now.
Krishna's birth tallies well with archeological findings at submerged Dwaraka. The Harappan findings tally with a date later than Krishna's times, giving momentum to the notion that the settlers at Saraswathy river-bank were the dis-located people of Dwaraka due to inundation of Dwaraka. From the description in Mahabharatha we know that the people of Dwaraka moved North along the Saraswathy river and settled enroute.
The impotant corroborative evidence I mentioned above on Rama's times is from astrology. The astro-birth details of Rama are accurate in that we can not only construct the horoscope of Rama but also substantiate the events in Rama's life in line with the dasa-antar dasa preditions of Rama's horoscope. We can establish that every event that happened to Rama tallies well with the dasa predictions of Rama's horoscope. I will write about this when I do a detailed series on Rama's times.
What must not be lost sight of is that the 4 vedas existed even at Rama's times. Rama had learnt all the 4 vedas. If the Rig veda is supposed to have been evolved at around 3000 BC and the Atharvan veda at a period later to this, how could have Rama learnt them in 5000 BCE?
Any dating on vedas can not be used to compartmentalise the past as vedic or pre-vedic etc. The dating can only give additonal impetus to pushing back civilisation in the Indian land mass to far closer to the end of Ice age!
Prof Achar's analysis has given this impetus!
To say on the basis of dating of the currently avilable vedas that they were evolved only a few thousands of years ago is wrong. In the comity of such little understanding of the Vedic past, Prof Achar has done well in bringing out the date of some of the avilable hymns with solid evidence.
