Now if one finds the Moolabandhasana posture in 9000 BC,how can one date Yoga Sutra of Patanjali at 400 BC?
And this Yoga has been in vogue in the south of Vindhyas in India and was based on Yoga Sutras.
This means that the south was very much in tune with Sanatana Dharma and was a part of Sanatana Dharma. Patanjali is one of the Eighteen Siddhars of Tamil, it can be postulated that Yoga and Sanatana Dharma was present in the South,Dravida Desa at the time of Rig Veda and the Sarasvati River in full flow.
Which means that the Dravida culture is at least 10,000 years old as Sarasvati River and The Rig Veda are dated around the same time.
