Let us put aside astral projection for the time being and talk about something very few of us have achieved such as pure mental discipline. People such as Tibetan or Buddhist monks who have the mental discipline after much training, to lower their heart rates to literally a zero beat. Perhaps the body could be viewed as a machine, and we have control over it. Maybe it isn't control gained through a conscious awareness as such more a subconscious ability, dorment within all of us. Has anyone konwn anyone or have they themselves been taught...such mental discipline ? Please share your thoughts as I'd be fascinated.
