The Spectrum of Consciousness UP130

Ken Wilber's groundbreaking synthesis of religion, philosophy, physics, and psychology started a revolution in transpersonal psychology. He was the first to suggest in a systematic way that the great psychological systems of the West could be integrated with the noble contemplative traditions of the East. The Spectrum of Consciousness, first released in 1977, has been the prominent reference point for all subsequent attempts at integrating psychology and spirituality.
