This book is the first consistent theological treatment of the subject of Hindu thought known to itself as Trika or Triadism. Few Indic theologies equal it in architectonic power and mystical profundity. It's a very complicated system but Murphy has made every effort to render it all intelligible. Some chapter headings include: History and Metaphysics; Gnostic Triadism: the Ways to Liberation (yogic practices and mystical formulas); The Energetic Way: Absorption in Energy (The Mystical Centres and the Coiled or Serpentine Potency), Mystical Realization, Ritual Sex (including the ritual itself); The Dark Night of Mystical Awakening; and much more.
