“Seth material” search engine (Jane Roberts)

There are many portions of the self, as you know. They do assume a form that is visible within their own dimension. These portions of the self are all simultaneous; in various stages of consciousness you become aware of other portions of the self, and an I identifies itself with one or another of these.

Since these selves exist simultaneously, it is then possible for consciousness to enter, or really form, such an image, undergo experiences within the characteristic pattern of reality, and then project to another image. In all cases consciousness forms the image. When consciousness changes, or travels at certain frequencies, it automatically changes its form. It is indeed possible to be involved with more than one form at once as in usual projection.

You can enter a trance state in any form, you see. The time element is important when you project from the physical image. It becomes less important the further away you get from the physical form. Since all of these selves are simultaneous, it is also possible to project yourself into one of your own previous identities.
