Accessible and thought provoking, this unique interpretation posits that an individual’s sense of self as a single, permanent being is an illusion and that each person is rather a collection of diverse personalities unified by common experiences. Far from being a hindrance, however, these multiple selves are a necessary mental mechanism to deal with an ever-evolving world. Through extensive exercises, graphs, and illustrations, this groundbreaking study demonstrates how to achieve harmony among these distinct personalities—avoiding the stress-inducing conflict that can often result between them—in order to fully harness their strength and potential.
