The unconscious is a marvelous universe of unseen energies, forces, forms of intelligence-even distinct personalities-that live within us. It is a much larger realm than most of us realize, one that has a complete life of its own running parallel to the ordinary life we live day by day. The unconscious is the secret source of much of our thought, feeling, and behavior. It influences us in ways that are all the more powerful because it is unsuspected.
