*Evidence substantiating information found in Puranas and Ithihasa, Ramayana and Mahabharata are now being validated by Astronomy, Astroarcheology , Epigraphy, Archeological finds, Tectonic plates movements,C4dating, Infra-red analysis, Stratification studies.
Before going into the Research find,let us look at some seemingly contradictory facts mentioned in the Puranas and Ithihasa.
And cross check them with references in ancient Tamil literature.
1.Vasishta appears in Ramayana and not much of him is heard since.
2.Yet , Vasishta is one of the Sapthapathi,who are eternal.
Atri,Bhrigu,Kutsa, Vasishta,Gautama,Kashyapa and Angirasa
3. Vasishta is found in Ancient Tamil literature.
4.Though Sanatana Dharma is reported to have sprung from the north of the Vindhya Mountains,latest finds prove that the Founder of Ikshvsku Dynasty, Ikshvsku’s Father Manu was from the South of Vidhyas.
5..Emperor Aja of Ikshvsku clan married a Pandya princess from South.
6.Chola kings of South trace their lineage to Ikshvsku Dynasty.
7.Cholas call themselves from Kashyapa Gotra.
8.Sage Viswamitra banished his sons to Dravida Desa,south of Vindhya.
9. Their descendant Apasthamba composed the Apasthamba Sutras, which are followed by Brahmins of South India.
10.Parashurama settled families from Dwaraka to Kerala.
11.Sage Agastya settled seventy two families on the present border area of Tamil Nadu and Kerala.
12.The Tamil homeland Lemuria is 230 million years old.
13. Rama refused to wage war against the Dravidas as they were his ancestors.
14. Lord Rama fought with the Atlantis people at seven Rishi valley currently in Pakistan
15.Chola king SibiChola king Sibi ruled from the present NWFP of Pakistan.

He was ancestor of Lord Rama.
He built a temple for Vishnu as Pundarikaksha at Thiruvellarai near Srirangam, Tamil Nadu.
16. When a Tsunami struck south,Lord Shiva,Ganesha and Vasishta migrated to Arctic via what is now middle East, Europe,America.
Then they reentered India.
One must remember the landmass then, was different from what it is today.
18. Sanatana Dharma was present throughout the world.
19.People of Bharathavarsha were spread throughout the world.
20. They remigrated from wherever they were to the present India,mostly from Sumeria.
21. Names of Dasaratha,Rama and Bharatha are found in Sumerian Kings List.
Now the research on Vasishta and Kaundinya Gotta migrated from middle East towards India , South India through Bolan Pasd.
This study is based on DNA presence.
It is notable that Rig Vedic Book 7 is ascribed to the sage Vasishta, whose affiliation with the mainly Iranic sun-worshipping Mitra-Varuna tradition is nevertheless codified in the Hindugotra system and became especially popular in the medieval assimilation of sun-worshipping Iranic peoples (Huna, Maitraka, and Gurjar) in Gujarat and the Western states . LPK Brahmins follow the Kaundinya gotra of the Vasishta group. Moreover, Brahmins of the Vasishta gotra occur in significantly higher numbers along the western side of the subcontinent (Supplementary File S42). Taken together, these observations support the possibility of Mitra-Varuna antecedents for LPKSTR LPK families..
