The Atman Project: A Transpersonal View of Human Development (1980) unites Eastern and Western approaches into a single, coherent framework, integrating views from Freud to Buddha, Gestalt to Shankara, Piaget to Yogachara, Kohlberg to Krishnamurti. Up from Eden: A Transpersonal View of Human Evolution (1981) describes evolution as a magnificent journey of Spirit-in-action, drawing on theorists from Jean Gebser to Jürgen Habermas. The essay "Odyssey: A Personal Inquiry into Humanistic and Transpersonal Psychology" and a New Age interview with Ken Wilber.
