In this book, Michael Washburn provides a psychoanalytic foundation for transpersonal psychology. Using psychoanalytic theory, Washburn explains how ego development both prepares for and creates obstacles to ego transcendence. Spiritual development, he proposes, can be properly understood only in terms of the ego development that precedes it. For example, many difficulties encountered in spiritual development can be traced to repressive underpinnings of ego development, and significant gender differences in spiritual development can be traced to corresponding gender differences that emerge during ego development.Washburn draws on a wide range of psychoanalytic perspectives in discussing ego development and uses both Eastern and Western sources in discussing spiritual development. In rethinking transpersonal psychology in psychoanalytic terms, he explains how essential elements of Jungian thought can be grounded in psychoanalytic theory.
