From the edgarcayce.org:
"The Akashic Records or "The Book of Life" can be equated to the universe's super computer system. It is this system that acts as the central storehouse of all information for every individual who has ever lived upon the earth. More than just a reservoir of events, the Akashic Records contain every deed, word, feeling, thought, and intent that has ever occurred at any time in the history of the world. Much more than simply a memory storehouse, however, these Akashic Records are interactive in that they have a tremendous influence upon our everyday lives, our relationships, our feelings and belief systems, and the potential realities we draw toward us."
