Dear writer: From my understanding astal projection is conducted by voluntarily shutting down or slowing down basic life metabolic proceses to concentrate blood to the brain. The most usual drain on our blood supply is our digestive track. There is some evidence that people with lower metabolic rates outlive those with higher metabolic rates. The science of lowering metabolic rates is very much a practice of hindu yogis. I don't think its a good idea for obvious reasons. As another writer mentioned the radio show or website
www.coasttocoast am. frequently has guests addressing remote viewing. Remote viewing was somewhat pioneered by a person named Engel Swann (not certain of the spelling on that one) and further refined by a gentleman of quite renown as Major Ed Dames. The remote viewing does not include a slowing down of life processes, but rather seeks to discipline thought patterns through basic protocols. Again in my opinion, you willgain better psychic and communication skills from this website than anywhere else.
