This is a genuine question, not trolling or being facetious, so please don't jump on me.
The Buddha achieved nirvana, yes? My understanding of nirvana is peace, bliss, no rebirth. Yet does the Buddha not say that he will return? Moreover, if achieving nirvana severs ties to this world, how is that the Buddha can interact with us, if he does at all? That is, if the Buddha is gone, to coin a phrase, is it only superstition that makes people pray to him, and even to other buddhas. Is there any point in invoking them through mantras, e.g. Medicine Buddha mantra?
Maybe I should know the answers, but it escapes me right now.
