unlike you i dont share the same optimism for a oneness of all religion. As there are "religions" that may have started from BS. just because its ancient doesnt mean it wasnt started out of whim. Alot of "occultic" stuffs today are really just BS, conspiracy theories. , make up stories, histories gone wild,
written by the talented and bought by the totally bewildered.
In kabahalah the absolute is the Ein Sof, in hindu is brahman, in plotinus The One, in Taoist its the Tao, in Zen the absolute Mind is non-mind, Christianity its the Trinity, et al.
