“Seth material” search engine (Jane Roberts)

Certain chemical changes must come about in the physical organism before projection can occur. Were it not for these, you would still be imprisoned within the corporal image. You know that dreaming has a definite chemical basis, that chemicals built up during period of waking experience are released through dreams. Not only are these released, but they form a propelling action that allows energy to flow in the opposite direction. As chemical reactions allow the body to utilize energy and form physical materializations, so the excess built up becomes, then, a propelling force, allowing action to flow in what you would call subjective directions.

Released they must be, or the organism would not survive. Periods of intense activity may also generate this additional chemical propellant. Although this is generated through activity, it is released, making projections possible, in alternating periods of quietude and rest. There must be a disciplined focus, therefore, of this propellant. Periods of heightened sexual activity of a strong and deep nature will help. Periods of no sexual activity will also help, however. On the one hand, the chemical excess is built up as a result of great intensity, and in the latter case it is built up because psychic and sexual release has not been granted.
