I don't know much about AP, I read a little when I first started studying magic, but just the very basics. Now I've been reading some of these threads and other random Google info, and they've given me more information. But I'm still wondering why? What exactly are the benefits of AP? I ask because as I understand it, you leave your body near death, and some people report having trouble getting back. Incidentally, I've read the same of hypnosis (trouble getting back), and wonder what are the similarities and differences between the two?
Well I dont know about hypnosis but I can answer why I Astral Project.
1.Knowledge, you can learn a great deal about magick from spirits. About 50% of my magickal knowledge I was taught or atleast expanded upon by spirits on the astral plane.
2. Somthings I could do with a ritual I could do (Some times faster and easyer) with Astral Projection. For an example: Theres a harmfull spirit who has been harasing family, myself, and my magick. I could do a ritual to banish it, but instead I attack it with my spiritaul body on the astral level. For me, I have found this works rather well.
I also agree with Luna runes as some of my objectives, but there is also past life insight. I also use it in meditation, speaking and connecting with my gods and goddess.
I don't know a lot about hypnosis, but I think that lucid dreaming is a branch of AP. Lucid dreaming is useful for much of the same objectives, but i found it easier when I started our.
