Q: You don't think that there are some profound connections with later Hinduism, like bathing in the water, or the yogic figure on some of the seals?
A: This has no doubt been the interpretation given by Sir John Marshall given in his book  when he wrote and described the religion of the Indus people. But that was because he knew the Hindu religion and society, and on that basis he interpreted, and called it, for example, the prototype of Shiva, and about talked about the yoga and so on. But today we know that there is a very great difference between the two. Certainly yoga continued, but it is possible that it continued even later on [outside Hinduism] for it is simply a question of meditation. For example, when I talk about the meditation derived in Islam today among the Sufis, and when I say it is derived from Buddhism, all the Muslims say no, it is nonsense to say that, but I know it is a derivation. It is quite possible something may have continued, but very little is known.
For example, image worship was known in the Indus Civilization but not known to the Aryans. The Aryans were the conquerors, but the people may have continued that. Similarly, yoga probably was not known to the Aryans in the earlier phases, but later it did penetrate into their society, maybe taken from surviving traditions among the common people. But who were those people, we do not know.
