The Spectrum of Consciousness

The Spectrum of Consciousness (1977)--one of the founding texts of transpersonal psychology--introduces the full-spectrum model, showing how the psychological systems of the West can be integrated with the contemplative traditions of the East. No Boundary: Eastern and Western Approaches to Personal Growth (1979) is a simple yet comprehensive guide to psychologies and therapies available from both Western and Eastern sources. Several important early articles: "The Psychologia Perennis," "Are the Chakras Real?" and "Where It Was, I Shall Become.".
