Personal development is largely growth of our Shadow selves--our adaptive unconscious in which resides our deepest senses of self, morality, intimacy, vulnerability, and spirituality. Shadow Light offers a wealth of research, ideas, and practices to help us grow our Shadow selves and accelerate personal evolution. This Shadow material is generated in less than a tenth of a second, and our conscious selves become more or less aware of it after one or two seconds, leaving our conscious awareness always one step behind the non-conscious flood of Shadow material.
