Hi! @biddle. Have you ever checked out any school of Buddhist meditation? According to the Theravada tradition, there are texts on various methods of meditation, about 44 methods if I can remember correctly.
There are many stages of development; the fist four stages are considered easy. Once one goes through the upper levels; each level will give the person clairaudience, clairvoyance, recalling of past lives, seeing into future lives, etc. All the paranormal will become normal. But the Buddha always forbade monks from getting attached to these special abilities. The goal is for enlightenment, not to spend time playing all the tricks.
Do be careful when trying to condition the mind. Jung, C.G. had given warnings and he had written quite a bit on his own psychic ability.
Cheers.
I haven't really, but I'll definitely read up a little bit about that when I have time; I've always been interested in different spiritual practices and their effects. I'm always interested in learning more about what reality, the universe, and life is all about. I also appreciate the words of caution and advice! :)
