“Seth material” search engine (Jane Roberts)

Now 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 corporeal image. You know that dreaming has definite chemical bases, that chemicals built up during periods of waking existence are released through dreams. Not only are they 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 then becomes a propelling force, allowing action to flow in what you would term subjective directions.

Projections involve many more aspects of the whole self, and are a mark that the personality is progressing in important ways. The inner senses are allowed their greatest freedom in projection states, and the whole self retains experience that it would not otherwise. When this knowledge becomes part of the usual waking consciousness, that is when you realize what you have done, then you have taken a gigantic step forward.

One small point, however. You project also while you are in the waking state, but you do not realize this. Training can help you however, though this involves more work, and you will not reach that stage of realization for some time.
