This is what we "metaphysicians" are saying. BH, if you think we're somehow trying to disprove modern science using ancient wisdom, you still have an incorrect notion of what Tradition is; what we're trying to do, at the very least, is to bring modern science "back into the fold", as it were: to reveal to the physicalists that reality is, in fact, far larger than just this physical universe. Accepting that there are multiple (actually infinite) other universes (like or unlike this one) is a good step on the way. Even so, this falls strictly under the doctrine espoused by us "metaphysicians": that everything is One, and that there is contained within that One all things, all potentials, all possibilities.
