Helena Blavatsky’s The Secret Doctrine, Vol. II: Anthropogenesis (1888) outlines the esoteric, spiritual evolution of humanity over millions of years, challenging Darwinian theory by proposing a conscious, involutionary process. Based on the Stanzas of Dzyan, it details the development of7 "Root Races," detailing humanity's transition from ethereal, asexual beings to physical, sexual beings across massive geological timescales. Anthropogenesis is the second part of her magnum opus, which together with Cosmogenesis, aims to provide a comprehensive, hidden history of humanity's origins and destiny.
