A seminar on the essential tantric symbol EVAM, which is an expression of the union of the feminine principle, or space (E), and the masculine principle, or unchangeable nature (VAM). Chogyam Trungpa goes through the meaning of this symbol in all three levels, or yanas, of Buddhist teachings: hinayana, mahayana, and vajrayana. (Note: These six talks were presented as a follow-up to "The Feminine Principle" seminar, which was a prerequisite to and laid the foundation for these teachings. Both seminars are included in the book, Glimpses of the Profound.)
