Hi there, could you tell me what Rasa Tantra means and how it is proven to relate to urine therapy? Im not skeptical in any way, I am just curious and find all this extremely interesting. I find both UT and alchemy fascinating. I know that 'rasa' means juice or essence, and that 'tantra' means to weave. Where does 'Rasa Tantra' itself originate from? Thanks. Stephen.
