Centers
The bodygraph has nine centers — energy/information hubs rooted in the chakra system, adapted for the nine-centered form. Each has a theme; defined (colored) vs open (white) changes how you live that theme and how conditioning enters.
Think of centers as communities linked by channels; definition is the reliable wiring between them (see definition).
The nine centers
| Center | Theme | Note |
|---|---|---|
| Head (Crown) | Inspiration, mental pressure, questions | center-head |
| Ajna (Mind) | Conceptualizing, opinions, certainty | center-ajna |
| Throat | Expression, manifestation, communication | center-throat |
| G (Self) | Identity, direction, love | center-g |
| Heart (Ego) | Willpower, worth, promises | center-heart |
| Solar Plexus (Emotions) | Feelings, emotional wave, desire | center-solar-plexus |
| Sacral | Life force, work energy, sexuality | center-sacral |
| Spleen | Intuition, health, survival in the now | center-spleen |
| Root | Adrenal pressure, stress, drive to finish | center-root |
Defined vs open
| State | Defined (colored) | Undefined / open (white) |
|---|---|---|
| Energy | Consistent, reliable; you broadcast | Inconsistent internally; amplify others |
| Wisdom | Live your theme steadily | Learn via patterns over time |
| Conditioning risk | Assume everyone shares your fixed theme | Absorb others’ definition as “yours”; mind decides from openness |
Open (undefined with no gates touching the center) is especially receptive. IHDS teaching: each open center has a not-self strategy that impacts mental decision-making when the mind leads instead of type-strategy and authority.
Genetic attraction
Humans are pulled toward what they are not — a genetic law for the gene pool that also fuels conditioning in white centers. Strategy sidesteps the trap; centers explain where amplification hurts.
Type and authority connection
types depend on Sacral definition and motor→Throat wiring — not on how many centers are defined (except reflector with none).
authority follows defined Solar Plexus, Sacral, Spleen, Heart, or G (strategy field in humandesign.chart).
channels connect two centers when both end gates are active across personality and design.
