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. "The aim of this work may be thus stated: to show that Nature is not 'a fortuitous concurrence of atoms,' and to assign to man his rightful place in the scheme of the Universe; to rescue from degradation the archaic truths which are the basis of all religions; and to uncover, to some extent, the fundamental unity from which they all spring." — Preface . Based on the ancient Stanzas of Dzyan (see link below) with corroborating testimony from hundreds of 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.
