The Secret Doctrine, Helena Petrovna Blavatsky's masterwork on the origin and evolution of the universe and humanity itself, is arguably the most famous, and perhaps the most influential, occult book ever written. Published since 1888, it has long eluded the grasp of modern readers until now. A sourcebook of the esoteric tradition, outlining the fundamental tenets of the Secret Doctrine of the Archaic Ages. This title 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.
