“Seth material” search engine (Jane Roberts)

The tissue capsule of which I have spoken earlier surrounds every living consciousness. To some extent it could be compared to an extra layer of skin surrounding the physical body, except that it is not constructed in the same manner upon your plane, and is invisible to you under ordinary circumstances.

These capsules can be seen by you under certain circumstances, and have been called astral bodies—a term which does not meet with my pleasure. I would like to repeat again the fact that in many instances, and with exceptions, ideas not fully constructed on your plane not only have great force but are also freer from the effects of physical laws. The idea has at its command then greater and varied methods of expression, and from it varieties of construction can be attempted. I have mentioned the advantages of a painting over a piece of sculpture, and an idea not fully captured will find further expression.

It is this sense which directs your own growth physically, and which forms the cells of your physical body and constantly changes the stuff of your body.

Now this does not mean that a stationary body of any kind cannot materialize itself upon another plane. And if it does, it of necessity must in some manner surround itself with the constructions or camouflage of the particular plane which it attempts to enter. This takes a high level of inner development.
