A vaguely disquieting sense of metaphysics as it seems to appear in Buddhism nibbles at my toes from time to time, and I would like to know how others view this issue. I am referring here primarily to the idea of karma and rebirth as understood literally, that is, viewed as extending beyond this present lifetime.
The idea is rather compelling as an extension of what we can see in our present lives, both mental and physical, but that hypothetical extension is pure metaphysics, can neither be proven nor disproven, and is thus - as I understand the Buddha's teaching - an unprofitable topic for discussion. ( Hence I invite you to discuss it - go figure. )
What is your view of karma and rebirth and any other apparently metaphysical propositions that you have encountered in your study of Buddhism?
