The BodyGraph is your precise energetic blueprint — calculated from your exact birth data. It shows your 9 Centers, 36 Channels, and 64 Gates: the complete architecture of how your energy is designed to flow, where you are consistent, and where you are open to the world.
The Human Design BodyGraph — also called the "Rave BodyGraph" — is the visual representation of your unique energetic design. It is a precise, calculated map, not a generic personality profile or astrological interpretation. Every detail is derived from your exact birth date, time, and location using Ra Uru Hu's original Maia Mechanics calculation.
The BodyGraph shows which of your 9 energy Centers are defined (colored in, consistent energy) and which are undefined (open, receptive, influenced by others). The pattern of definition — which centers connect to which via Channels and Gates — determines your Type, Authority, and Profile.
This is not metaphor. The BodyGraph is a mechanical description of your energy architecture — how your energy is generated, directed, and expressed. It is as specific to you as your DNA.
The Human Design System uses a 9-Center model — an evolution of the 7-chakra system that reflects the neutrino mutation of 1781. Each center has biological correlates, specific themes, and an energetic function.
The pressure to think, question, and inspire. Not a decision-making center. When defined: consistent mental pressure. When undefined: amplified confusion and borrowed inspiration.
The mind's processing center — analysis, concepts, and certainty. When defined: fixed ways of thinking. When undefined: flexible but susceptible to mental conditioning.
The center of expression and action. The most important center for manifestation. All energy ultimately seeks to reach the Throat — how it gets there determines your Type.
The seat of identity, love, and direction in life. When defined: consistent sense of self. When undefined: identity fluctuates with environment — and that is by design.
The willpower center — promises, commitments, and the tribal material world. When defined: consistent willpower. When undefined: willpower is not reliable for decision-making.
The emotional wave center. When defined: emotional Authority — decisions require riding the wave to clarity. Never in the now. The most powerful center in the chart.
The Generator's life force. When defined: sustainable work energy and Sacral response. When undefined: no consistent access to sustainable life force energy — not a Generator or Manifesting Generator.
The oldest awareness center — survival, immune system, and in-the-moment intuition. When defined: consistent immune awareness. Splenic Authority speaks once, in the moment.
The pressure center at the base — adrenaline, stress, and the drive to get things done. When defined: consistent pressure. When undefined: susceptible to rushing or being driven by others' urgency.
The single most important concept in reading a BodyGraph is understanding what it means for a center to be defined versus undefined.
Defined centers have consistent, fixed energy. They operate the same way regardless of who you are with, what environment you're in, or how you feel. This is your reliable, authentic energy — what you bring to others. Your Type and Authority are determined by which centers are defined and how they connect.
Undefined centers take in, amplify, and reflect the energy of others. They are not weaknesses — they are your deepest sources of wisdom about those areas. The risk is conditioning: being influenced to act as if that energy were your own. Deconditioning means learning to experience undefined centers without being driven by them.
A Channel in the BodyGraph is formed when two Gates — one in each of two adjacent Centers — are both activated. Channels create definition: they color in both of the centers they connect and create a consistent energy flow between them.
There are 36 Channels in the Human Design BodyGraph. Each channel has a specific theme and function. The pattern of which channels are active in your chart determines your Type (whether energy reaches the Throat and how), your Split or Single Definition (whether your definition is one connected circuit or separated components), and your overall energetic profile.
Channels are organized into three Circuits — Individual, Tribal, and Collective — each with its own purpose and frequency pattern:
Each of the 64 Gates corresponds directly to a hexagram of the I Ching — a specific frequency of human expression. Gates are activated by planetary positions at the moment of birth (Personality — conscious) and 88 solar degrees before birth (Design — unconscious).
A Gate that is activated but not connected to a Gate in an adjacent Center creates a Hanging Gate — potential energy waiting for activation from another person or transit. This is one mechanism through which we attract specific people into our lives: they activate our hanging gates and complete our circuits.
Gate activations determine your Profile (the two lines visible in your conscious Sun/Earth and unconscious Sun/Earth positions) and contribute to your Incarnation Cross — the overarching theme of your life's purpose.

The birth time determines which gates are activated in your Conscious (Personality) calculation.
Split definition means your defined channels form two or more separate "islands" — they are not connected to each other internally. A Single Definition has all defined centers connected. A Split Definition has two separate components. A Triple Split has three. Split Definition people are drawn to others who can bridge their splits — a key factor in relationship dynamics.
Yes. The terms "Human Design chart" and "Human Design BodyGraph" refer to the same thing. The BodyGraph is the visual diagram. Your chart includes the BodyGraph diagram plus all the gate activations, channel information, Centers, Type, Authority, Profile, and Incarnation Cross — the complete calculated output.
An astrological birth chart maps planetary positions to zodiac signs and houses — it interprets themes and archetypal influences. The Human Design BodyGraph uses planetary positions to activate specific gates in a 64-gate system derived from the I Ching. It produces a precise energetic architecture — your Centers, Channels, and Type — rather than symbolic interpretations. Human Design uses two calculation points: birth and 88 solar degrees prior, yielding both a Personality and a Design.
You can learn the mechanics and begin to understand your chart — the Jovian Archive courses are the most complete resource for this. However, the nuance of how your specific combination of Gates, Channels, Centers, and Definition interact is best understood through a reading with a trained analyst.
