The Human Design System is the complete body of knowledge received and transmitted by Ra Uru Hu beginning with the 1987 REVELATION. It encompasses the full spectrum of human mechanics: the 9 Centers, 64 Gates, 36 Channels, 4 Types, 6 Lines, 12 Profiles, 192 Incarnation Crosses, the mechanics of Strategy and Authority, Variable (PHS — Primary Health System), Rave Cosmology, and the Dream Rave. The system operates at multiple levels of depth — from the foundational (Type/Strategy/Authority) that anyone can apply immediately, to the advanced layers (Variable, Cosmology) that require years of study and experimentation. Ra consistently taught that the System is meant to be lived and tested, not merely intellectually understood. Jovian Archive is the official steward of Ra's original teachings.
