Human Design

A modern system that overlays the I Ching on two birth charts to assign a fixed Type, Authority, and Profile, mapped onto a nine-centre body diagram. The mechanics are computed; the guidance is interpretive.

Human Design, synthesized in the late 1980s, combines astrology, the I Ching, the chakra system, and the Kabbalist Tree of Life into one diagram called the BodyGraph. It uses two charts: the Personality chart (the sky at birth) and the Design chart (the sky at the moment the Sun was exactly 88° of arc earlier, roughly 88 days before birth). In each chart, thirteen bodies fall into the 64 gates — the zodiac divided into the 64 hexagrams of the I Ching — and into one of six lines within each gate. When both gates of a channel are activated, the two centres it connects become 'defined'. From the pattern of defined centres come the three headline results: Type (Manifestor, Generator, Manifesting Generator, Projector, or Reflector), Authority (the centre you're advised to make decisions from), and Profile (the pair of lines carried by the two Suns). The calculation is deterministic and checkable — the 88° Design moment, the gate wheel, the channels, and the centre map are all fixed. What a Type, Authority, or defined centre is said to mean, and the strategy attached to each Type, is Human Design's own interpretive framework, not a measured fact. Because it depends on the exact birth minute, an accurate chart needs a known birth time.

Not: Human Design is not a scientific finding and not a fixed verdict on what you can do. It is a symbolic map with a large interpretive vocabulary layered on real astronomy. It is also not the same as your astrology chart, though it is computed from the same planetary positions.

The Type, Authority, and Profile are computed exactly from verified tables, but the birth time matters — the Moon and the Sun's line move quickly, so a chart with an uncertain time can shift. The meanings and strategies are interpretive convention, not demonstrated effects.
