“Seth material” search engine (Jane Roberts)

When you enter a different dimension, the abilities of the body form change, and for all intents and purposes, it is a different body form — which we will now call a mind form. It still seems physical in shape, but you can walk through physical matter with it. You can levitate much more freely, traveling within the solar system. But you cannot go further with it.

The third we may call the true projection form. In it, it is possible to travel beyond your solar system, and to perceive the past, present and futures of other systems as well as your own. The various forms that you use do not dictate your experience, however. You may begin in one form and change to another — or go from the first to the third. On such occasions you must pass through in reverse direction [on returning]. The forms merely represent stages of consciousness.

Now, when you project from the dream body, consciously you are already outside of the physical one. You have already made the initial change away from physical focus. The mass of valid projections are made from the dreaming body. When the excursion is over, the return to the dream body is made with no strain, you see, for the ego is little concerned. In many such cases, however, the knowledge is not available to the waking self.
