Continuously in print for over 100 years, the SD remains today the most comprehensive sourcebook of the esoteric tradition, outlining the fundamental tenets of the Secret Doctrine of the Archaic Ages. Challenging, prophetic, and strikingly modern, it directly addresses the perennial questions: continuity of life after death, purpose of existence, good and evil, consciousness and substance, sexuality, karma, evolution, and human and planetary transformation. Based on the ancient Stanzas of Dzyan with corroborating testimony from over 1,200 sources, these volumes unfold the drama of cosmic and human evolution -- from the reawakening of the gods after a Night of the Universe to the ultimate reunion of cosmos with its divine source. Supplementary sections discuss relevant scientific issues as well as the mystery language of myths, symbols, and allegories, helping the reader decipher the often abstruse imagery of the world's sacred literature.
