The Story of Man is a history of the great spiritual traditions, which, over the millennia, have added immeasurably to the depth and richness of the human experience. Their number includes the ancient Sumerian priest caste, the Order of the Egyptian Temple-Priests, the Chaldean Magi, the Vedic Rishis, the Vajrayana Buddhist lineages, the prophets of the Judaic tradition, the Apostolic Christian schools, and the many Sufi Orders of Islam.
