Originally from the Vedas, she is actually an avatar of the Vedic deity called Avalokitesvara. Who is apparently one of the avatars of Shiva as well, if I remember correctly from Joe Shearer's post.
does this mean that the religious contact between india-china happened before buddhism?

or does it mean buddhism was a spin off to balance certain issues in hinduism ?
