Demetra,
The author describes your Higher Self as a collective body of energy. He describes the Force as an energy that experiences evolution -- is part of each and every thing in the physical plane -- immortal and never ending -- the inner light of "livingness" within all things.
It's a little book, only 73 pages and about $13.00 at the local book store. It can be found online for less.
Enjoy
