Learn about the Human Design System — how it combines astrology, I Ching, Kabbalah and quantum physics to understand your unique nature.
Human Design is a system of self-knowledge created by Ra Uru Hu in 1987. It combines elements of astrology, the I Ching (Book of Changes), Kabbalah (Tree of Life), the Hindu chakra system, and quantum physics into a single map — the bodygraph.
Unlike astrology, which describes character through zodiac signs, Human Design provides a concrete decision-making mechanism. Your bodygraph shows how you process energy, where you are stable, and where you are susceptible to outside influence.
How Does the System Work?
To calculate a bodygraph, you need your date, time, and place of birth. The system performs two calculations:
- Personality — the moment of your birth. This is what you are conscious of about yourself.
- Design — approximately 88 days before birth. This is your unconscious, bodily nature.

Key Elements of the Bodygraph
Type
There are 5 types — Generator, Manifesting Generator, Projector, Manifestor, and Reflector. Your type determines your strategy for interacting with the world. Learn more about types →
Authority
Inner Authority is your way of making correct decisions. It can be emotional, sacral, splenic, and more. Learn more about authority →
Profile
12 profiles (from 1/3 to 6/2) describe your life role and learning style. Learn more about profiles →
Centers
The 9 centers of the bodygraph can be defined (colored) or undefined (white). Defined centers represent your stable energy. Undefined centers are areas where you are vulnerable to the influence of others.
Why Does It Matter?
Human Design helps you:
- Make decisions according to your nature, not societal pressure
- Understand your strengths and growth areas
- Improve relationships by understanding different types
- Find your path in career and business
- Raise children honoring their uniqueness
How to Get Started?
The first step is to calculate your bodygraph. Then learn your type and strategy, and start experimenting with it in everyday life. Explore our learning section for in-depth study of each element.
"Human Design is not something to believe in. It's an experiment. Try it and see what changes in your life." — Ra Uru Hu
What Strategy and Authority Look Like in a Regular Day
Strategy and Inner Authority start to feel less abstract once they land inside ordinary moments. A Generator who waits for the sacral response might be mid-conversation at a coffee shop when a friend proposes a spontaneous road trip, and instead of mentally listing pros and cons, they notice a soft "uh-huh" or a subtle tightening in the gut. The strategy is simply to honour that sound, and the experiment is to see whether acting on it produces less resistance the next day. A Manifesting Generator skips the waiting more often, but still checks the sacral before committing, then moves quickly to inform. A Projector, on the other hand, is usually not the one initiating the trip at all. The invitation tends to arrive, and the authority — perhaps emotional, perhaps splenic — decides whether the recognition of their gifts is real or performed. A Manifestor can rest into the peace strategy, announcing the plan and letting others adjust. The Reflector waits a full lunar cycle before making bigger moves, sampling the community's mood. None of this requires belief, only attention.
Common Misreadings and How to Tell Them Apart
The most frequent mix-up is treating Type like a personality test, sorting people into "Generators are workers, Projectors are guides" boxes. Type is mechanical, not moral. A Generator who launches businesses is still a Generator; the strategy of responding doesn't vanish. Another confusion is equating defined centers with "good" and undefined with "bad." Defined centers are simply reliable, fixed energy; undefined centers are amplification channels where wisdom can also come through, once the person stops trying to be the conditioned signal. Authority is sometimes misread as instinct in every case, but emotional authority specifically asks for clarity over time rather than a single flash. Splenic authority, by contrast, is immediate and quiet, and if someone is still talking themselves into a decision, it is not splenic. The simplest tell: strategy and authority should reduce friction. If experimenting makes life noticeably more complicated, the mechanic has probably been misapplied, not the system.
A Gentle Way to Begin the Experiment
Pick one low-stakes area — what to eat, which email to answer first, whether to accept an invitation on the spot. For two weeks, pause before acting and ask the body what the strategy and authority suggest, then note the outcome in a sentence or two. The point is not to get the chart "right" but to gather firsthand data. After the two weeks, compare the notes to a normal week. Most people find one or two patterns that feel obviously smoother, and those become the anchor for going deeper into the bodygraph, type, authority, profile, and centers described above. The system rewards patience, repetition, and honesty more than it rewards memorising terminology.
