Human Design splits two chakras into four centers. Which ones, why the mutation matters, and how defined vs open changes the whole model.
If you already know the traditional chakra system, the 9 centers on a Human Design bodygraph will look immediately familiar in shape and location, and that resemblance is intentional. Human Design chakras are one of the clearest borrowed layers in the whole system, adapted from the 7-chakra model into 9 centers with some renaming and one important structural split.
The chakra system comes from Hindu and Buddhist tantric traditions, describing seven major energy centers running along the spine from the base of the body to the crown of the head:
Traditionally, chakras are understood as spinning wheels of subtle energy that can be balanced or blocked, and much of yoga, meditation, and energy-healing practice is oriented around keeping them open and flowing.
Ra Uru Hu's Human Design bodygraph keeps the same general vertical layout but restructures the seven chakras into nine centers:
The two clearest structural changes are the split of the traditional Heart/Solar Plexus territory into three separate centers (G Center, Heart/Ego, and a redefined Solar Plexus) and the addition of the Spleen, which has no traditional chakra equivalent at all.
This is the most important conceptual difference, not just a naming change. In the traditional chakra model, all seven chakras are ideally open, balanced, and flowing; a closed or blocked chakra is treated as a problem to correct through practice.
Human Design does not treat undefined (open) centers as damaged or blocked. Instead, undefined centers are considered a source of wisdom and openness — places where you take in and amplify the energy of others, rather than generating a fixed, consistent theme yourself. A chart with many undefined centers is not "less balanced" in Human Design terms; it simply describes someone more receptive to and shaped by their environment in those specific areas.
| Feature | Chakra System | Human Design Centers | |---|---|---| | Number of centers | 7 | 9 | | Origin | Hindu/Buddhist tantric tradition | 1987 synthesis by Ra Uru Hu | | Ideal state | All chakras open and balanced | Defined and undefined centers both valid | | Unique additions | — | Spleen, G Center, split Heart/Solar Plexus | | Practice orientation | Balancing/opening through yoga, meditation | Understanding fixed definition from birth chart | | Change over time | Believed to shift through practice | Defined/undefined status fixed at birth (definition itself is stable, though some centers can show temporary "electromagnetic" connection in relationships) |
A frequent mistake is assuming an undefined Human Design center is equivalent to a "blocked chakra" needing to be healed or activated. In Human Design's own framework, that reframe is specifically rejected: undefined centers are not malfunctioning, and there is no chart-based worksheet for "opening" one, since Human Design considers center definition fixed at birth rather than a practice outcome. Similarly, calling the G Center or Spleen a "chakra" by the traditional definition overstates the connection, since neither has a direct one-to-one traditional counterpart.
Another point of confusion is location: while several centers sit close to their chakra counterparts, the G Center's placement and role (identity and direction, roughly where the traditional Heart/Anahata chakra sits) do not map cleanly onto love and connection the way Anahata traditionally does, since Human Design assigns most of that love/connection territory instead to the Heart/Ego center just below it.
If you come from a yoga or energy-healing background, your existing intuitive sense of the body's energetic geography will transfer reasonably well to reading a bodygraph. Just be prepared to release the "open is good, closed is bad" framework that governs chakra work, and replace it with Human Design's view that both defined and undefined centers describe a valid, functional way of being in the world.
Should I try to "open" my undefined centers like a blocked chakra? No. Human Design treats center definition as fixed at birth and undefined centers as a source of openness and wisdom, not a problem to fix through practice.
Is the Spleen center the same as any traditional chakra? Not directly. It has no clean traditional chakra equivalent; it was introduced in Human Design to represent instinct, immune-related awareness, and present-time survival intuition.
Why does Human Design split the Heart chakra into multiple centers? Ra Uru Hu's synthesis separated the broad love/willpower/identity territory traditionally held by the Heart chakra into three distinct centers — G Center, Heart/Ego, and parts of Solar Plexus — each governing a more specific function within the bodygraph.
If I already practice yoga or chakra meditation, should I stop because of Human Design's different philosophy? No. There's no requirement to abandon one practice for the other; many people continue chakra-based practices for their own value while separately using Human Design's centers for chart-based self-understanding, treating the two as parallel rather than competing systems.
Does having more defined centers mean a "more evolved" chart? No. Human Design does not rank charts by number of defined centers; Reflectors, for example, have no defined centers at all and are considered a distinct, complete type rather than an incomplete one, so definition count is not a measure of spiritual development or overall quality.
Consider a hypothetical person, Elena, whose chart shows a defined Sacral, defined Root, and defined Spleen, but an undefined Solar Plexus, undefined Heart/Ego, and undefined G Center. In chakra language, someone unfamiliar with Human Design might look at Elena's undefined Solar Plexus and assume something is "blocked" and needs opening through breathwork or meditation. Human Design reframes this completely: Elena's undefined Solar Plexus means she doesn't generate her own consistent emotional wave; instead she tends to amplify and absorb the emotional atmosphere of people around her, sometimes intensely. This isn't a flaw to fix — it's a specific kind of openness that, once recognized, helps Elena tell the difference between her own steady baseline (coming from her defined centers) and emotional weather she's picked up from someone else's mood (coming from her undefined Solar Plexus).
Meanwhile, her defined Sacral gives her a consistent, reliable source of life-force energy for work she's genuinely engaged with, and her defined Root gives her a steady relationship to pressure and stress rather than one that fluctuates with the room. Reading her whole chart together, rather than picking one center in isolation, is what makes the defined/undefined framework useful rather than just a list of traits.
1. [Generate your free Human Design chart](/chart) and note which of your nine centers are colored in (defined) versus white (undefined). 2. Lay your list next to the traditional seven chakras and mark rough correspondences: Head to Crown, Ajna to Third Eye, Throat to Throat, Heart/Ego and part of Solar Plexus to the traditional Heart chakra territory, Sacral to Sacral, and Root to Root. 3. Note that the Spleen and G Center don't have a clean one-to-one traditional chakra match; treat these as genuinely new territory in the Human Design model rather than forcing a match. 4. For each defined center, write one sentence describing how that theme shows up consistently for you. 5. For each undefined center, write one sentence about a time you noticed yourself being strongly influenced by someone else's energy in that theme's territory (for example, absorbing someone else's anger if your Solar Plexus is undefined). 6. Revisit the [centers](/centers) page for more detail on any specific center you want to understand more deeply, and consider how it connects to [channels](/channels) running through it.
For a month, each time you feel an intense emotional, willpower-related, or identity-related shift that seems to arrive suddenly from being around a particular person, write it down along with which of your centers is undefined in that territory. Many people doing this practice for the first time are surprised at how often the pattern lines up: an undefined Solar Plexus and sudden emotional intensity around emotionally expressive people, or an undefined Heart/Ego center and a sudden urge to prove your worth around certain competitive people. This kind of practice doesn't prove the underlying theory, but it gives you a concrete, personal way to test whether the defined/undefined framework describes anything real in your own daily experience.
A reasonable objection is that the traditional chakra system already includes ideas about chakras being affected by other people's energy (through concepts like energetic empathy or aura), so Human Design's undefined-center framework may just be repackaging an existing idea with new labels rather than adding something genuinely new. There's some truth to this: neither system's claims about energy transfer between people have been established through controlled scientific study, and much of the underlying vocabulary about "absorbing" energy predates both traditions. What Human Design does add structurally is a fixed, chart-based prediction of exactly which centers are open for a given individual, rather than a general principle that anyone can be affected by anyone else's energy in any area. Whether that added specificity reflects something real is, again, a question each person has to test against their own experience rather than settle through the theory alone.
| Traditional Chakra | Closest Human Design Center(s) | Notable Difference | |---|---|---| | Crown (Sahasrara) | Head | Head is about mental pressure/inspiration, not spiritual attainment specifically | | Third Eye (Ajna) | Ajna | Close conceptual match; both relate to processing and conceptualizing | | Throat (Vishuddha) | Throat | Close match; both relate to expression and communication | | Heart (Anahata) | G Center, Heart/Ego, part of Solar Plexus | Split across three centers instead of one | | Solar Plexus (Manipura) | Solar Plexus | Redefined around emotional waves rather than willpower alone | | Sacral (Svadhisthana) | Sacral | Close match; both relate to creative and life-force energy | | Root (Muladhara) | Root | Close match; both relate to grounding and survival pressure | | — | Spleen | No traditional chakra equivalent; new addition for instinct and present-time awareness |
