I imagine that would get pretty ugly. Especially if other people got wind of it. Your body would be put on life support probably. Unless you took it out into a cave in the desert or something. It would be hard not to have compassion for it, suffering and dying. That compassion alone would probably be enough to find yourself back in it. Well, you hear tales of Indian gurus who just sit in lotus posture and leave and don't come back. Eventually their body dies. So I suppose it's possible. I also prefer the astral to the physical, except that the physical is the locale of people I love and can't leave unless I have to. Also, and this is unprovable, but it's possible we have these bodies for reasons not always apparent to us. Once on the astral, there was a sort of committee, for lack of a better word, that was discussing my case, and I woke up, and then after I woke up, I heard one of the women say, clear as a bell, on the physical level mind you!, "She has to learn to live to infinity in the world". So, based on that (not very scientific!) evidence, taking matters into our own hands as far as death goes.......I dunno. Might be a mistake. You might find yourself back in a body even less to your liking faster than you can say boo, for that matter.
