With reference to your question concerning the Sabaean and Hindu religions: there is nothing in the Teachings that could help us in ascertaining which one of these two Faiths is older. Neither history seems to be able to provide a definite answer to this question. The records concerning the origin of these religions are not sufficiently detailed and reliable to offer any conclusive evidence on this point.
