The Human Design vocabulary, explained on one page

Published 2026-09-01 — 4 min read

Human Design has an entry problem: its vocabulary. A chart reading strings together technical terms within a few lines, and you can lose the thread before you've even grasped what was being discussed.

Here are the words that keep coming up, in the order you'll actually need them. Keep this page handy during your first readings.

Bodygraph

The drawing of your chart. A stylized figure filled with geometric shapes connected by lines, calculated from your birth date, time, and place. Everything else in the vocabulary describes one element of this diagram.

Center

One of the nine geometric shapes on the bodygraph. Each one governs a domain: communication, action, emotions, intuition, reflection, identity. The idea comes from the Indian chakras, reworked into nine instead of seven.

Defined center, open center

A defined center appears colored on the diagram. Its energy works in a stable, consistent way for you, regardless of circumstances.

An open center stays white. Its energy varies depending on the environment and the people around you. You pick up what others are putting out there, which explains why some days feel so different from the ones before.

Open centers are often the most revealing part of a chart, because they describe fluctuations that people usually mistake for personal inconsistency.

Type

Your energetic category, determined by the combination of your defined centers. Depending on the author, there are four or five: Manifestor, Generator, Manifesting Generator, Projector, Reflector. Type describes an energy mechanic. Two people of the same type can have completely opposite personalities.

Strategy

The way of engaging with the world that matches your type. Informing for the Manifestor, waiting to respond for the Generator, waiting for the invitation for the Projector, letting a lunar cycle pass for the Reflector. It's the easiest part of the system to test for yourself.

Signature and Not-Self

The signature is the pleasant feeling that comes with aligned functioning: peace, satisfaction, success, or surprise depending on the type. The Not-Self is its unpleasant counterpart: anger, frustration, bitterness, disappointment. These two markers act as a daily dashboard.

Authority

The way your body signals a yes or a no, before the mind has built its arguments. It stems from the configuration of your centers and is read according to a precise hierarchy. Some people have an emotional authority that requires waiting for clarity, others have an immediate answer coming from the gut or intuition.

Profile

Two numbers, from 1/3 to 6/2, that describe a way of learning and relating to others. There are twelve profiles in total. The first number corresponds to your conscious functioning, the second to what operates more quietly.

Channels and Gates

The Gates are the 64 numbers arranged around the bodygraph, inherited from the hexagrams of the I Ching. A channel connects two gates and links two centers. When a channel is complete, it colors the two centers it connects, making them defined.

Conditioning

Everything you've absorbed over the years without choosing it: family expectations, school norms, social pressures. The system holds that these influences end up covering over your spontaneous way of functioning.

Deconditioning

The work of identifying these influences in order to trust your own functioning again. A slow process, described as unfolding over several years, and nothing like a ten-step method.

Gene Keys

A related system, developed later from the same 64 hexagrams, with a more contemplative approach. Some readings incorporate it alongside Human Design.

What now

With these terms in mind, a chart reading becomes far easier to follow. If you're truly starting from zero, the beginner's guide covers everything from the start. To identify your type, the types guide gives a recognition clue for each one. And to understand your centers, the guide to the nine centers details what each one governs.
