This question may read a little philosophical, Buddhist, and personal.
I've been a little obsessed with death for a very long time, and feel like I have zeezen answer. Less interested in "the path" (I would like to practice zazen) than whether my conclusion is sound, though to an extent, if it is, I can go on my way. As well as whether it conflicts with any zazen practice. A Buddhist friend keeps telling me I'm afraid and trying to outsmart death, and they say nobody really knows, which I definitely sympathise with, but equally I believe I'm right.
So how can we know what will happen to us at death? Do we ask a teacher, ourselves, not ask about it, not worry about it, or something else entirely?
