This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.
Human Design traces its own origin to a single reported experience: Ra Uru Hu, the name adopted by Alan Robert Krakower, described receiving the system in Ibiza, Spain in 1987, and the Jovian Archive, the organization that presents itself as successor to his own International Human Design School, is the institutional source for that founding account today, carrying direct organizational continuity with his original teaching body.
That institutional account is a self account by an interested successor organization rather than independent biography or independent historical assessment, and the founding story it tells is not otherwise documented outside the system's own practitioner literature, a limitation an entry states honestly rather than treating the account as externally verified history.
The incarnation crosses themselves rest on Ra Uru Hu's own combination of the I Ching, Western astrology, the Kabbalistic tree of life and the chakras into a single construction of his own devising, not derived in a continuous documented line from any one of those older sources, so the study of how a specific cross's meaning was assigned is, at present, a study of the founding teacher's own text and its transmission through his successor organization rather than a documented multi century history of the kind an older tradition's practices can usually draw on.
