The Hindu way of life was part of that societal evolution. It was here the foundation of Hinduism possibly began without one single founder.
No initiator and no prime authorship have turned out to be distinctive boon for the Hindu faith. It has not bound itself with a consecrated originator. Without that revered barricade Hinduism got a clear passage to be in a progressive and evolutionary mode.
