Hinduism is like the Ganga, pure and unsullied at its source but taking in its course the impurities in the way. Even like the Ganga it is beneficent in its total effect. It takes a provincial form in every province, but the inner substance is retained everywhere.
You are all spirits. It is not that you "have" a spirit. To have a spirit implies that you are spirit and that you are also something else. Human beings are spirits. Being a human being is one of the ways of being a spirit.
Just be what it is that you are, and that is just fine. You don't have to be what you're not in any way. Live that and live that fully, and that is where you discover ecstasy. You can't really have ecstasy as something other than yourself
