Human Design

Human Design is a modern framework introduced in the late 1980s by the author known as Ra Uru Hu. It combines imagery and vocabulary drawn from several older systems — the I Ching’s sixty-four hexagrams, astrological placements, the Kabbalistic Tree of Life, and the chakra model — into a single diagram called a bodygraph.[1]

A bodygraph shows nine centres, thirty-six channels, and sixty-four gates, some coloured in (“defined”) and some left open (“undefined”). From that pattern the system derives an energy type — Manifestor, Generator, Manifesting Generator, Projector, or Reflector — along with a suggested strategy for making decisions and an inner “authority.”

People explore Human Design mainly as a decision-making and self-observation vocabulary: the strategies are practical prompts about pacing, initiation, and rest. Despite the language of “science” and genetics used in some Human Design material, it is a modern synthesis rather than a research-based system, and Birth Mosaic presents it that way.

This is a calculated chapter that requires birth date, exact time, and location, because the bodygraph uses two moments — the birth itself and a point roughly three months before it. Without a birth time, Birth Mosaic explains the framework but does not produce a bodygraph.

• Which energy type the framework would assign and what strategy it suggests
• How defined and undefined centres are said to shape consistency and sensitivity
• Decision-making prompts you can test against your own experience
• Where the borrowed symbols originally came from
• Which parts are modern invention rather than inherited tradition

Bodygraph

The chart diagram of centres, channels, and gates generated from birth data.

Type

One of five categories — Manifestor, Generator, Manifesting Generator, Projector, Reflector.

Strategy

The suggested way each type is advised to engage with opportunities.

Authority

The inner decision-making reference the chart points to, such as emotional or sacral.

Defined centre

A coloured-in centre said to work consistently; undefined centres are described as more variable.

Example: a chart with a defined sacral centre would be labelled a Generator, and the framework’s strategy for that type is to respond to what appears rather than to initiate cold. That is offered as a self-observation experiment, not a rule — and it is an example, not your result.

Human Design is a modern interpretive framework created in 1987, not an ancient tradition, and it is not supported by genetic or medical research. Its terminology varies between teachers and schools. Treat it as a reflective vocabulary rather than a diagnosis.
