The 9 Human Design Centers: Your Inner Energy Map (Beginner-Friendly Guide)

If you’ve pulled your Human Design chart and thought, “What are all these shapes?”—you’re in the right place.

Those shapes are your Centers. They’re the core of your "inner energy map": how you process energy, make decisions, experience emotions, and relate to the world.

In this guide, we’ll walk through:

What the 9 Human Design Centers are
The difference between defined and undefined/open centers
A simple breakdown of each center in real-life terms
How to start experimenting with your own inner energy map

First step: If you haven’t already, generate your free chart at https://humandesign.wtf so you can follow along with your own bodygraph.

1. What Are Human Design Centers?

In Human Design, Centers are the nine geometric shapes in your chart. Each one represents a specific aspect of your experience, such as:

Mind (ideas, opinions, concepts)
Emotions (feelings and emotional waves)
Identity (sense of self, love, and direction)
Energy and work (life force, stamina, and productivity)

They’re inspired by the Chakra system, but Human Design works with nine centers instead of seven. This shift reflects an evolutionary update in human consciousness (you can go deeper into this in the more advanced post: The 9 Human Design Centers Explained).

Defined vs. Undefined/Open Centers

When you look at your chart, some centers are colored in, and some are white.

Defined (colored)
- Reliable, consistent energy
- How you naturally express yourself
- What you broadcast into the world
Undefined/Open (white)
- Flexible, changeable energy
- Where you’re most influenced by others and the environment
- Potential for deep wisdom and conditioning

You’re not "supposed" to make all your centers defined. You’re not broken if you have many open centers. Your design is balanced exactly as it is.

2. Quick Overview of the 9 Centers

Here’s a simple snapshot so you can orient yourself:

Head – Inspiration, questions, mental pressure
Ajna – Concepts, opinions, mental processing
Throat – Communication, expression, manifestation
G Center – Identity, love, direction
Heart/Ego – Willpower, value, commitments
Sacral – Life force, work, sexuality, response
Solar Plexus – Emotions, desires, sensitivity
Spleen – Intuition, health, fears, survival awareness
Root – Stress, drive, adrenaline, timing

In the next section, we’ll go through each center one by one.

As you read, keep your chart from https://humandesign.wtf open and check: Is this center colored (defined) or white (undefined/open)? That will change how you experience it.

3. The 9 Centers Explained (In Real-Life Terms)

3.1 Head Center – Inspiration & Mental Pressure

Role: The Head is your inspiration and question center. It’s not here to answer questions; it’s here to generate them.

Defined Head
- Consistent way of thinking about big questions
- Often inspired in similar, repeatable ways
- May feel under constant pressure to resolve mental questions
Undefined/Open Head
- Picks up inspiration from everywhere
- Mind can feel busy or overwhelmed when around others
- Deep wisdom about which questions actually matter

Not-self pattern: Feeling like you must figure everything out or answer every question.

Gentle experiment:

Ask yourself: “Is this even my question?”
Let some questions remain unanswered and notice the relief.

3.2 Ajna Center – Mind & Concepts

Role: The Ajna is your mental processing and concept center. It’s about how you organize and interpret information.

Defined Ajna
- Consistent way of thinking and forming opinions
- Strong, reliable mental frameworks
- Can get attached to being "right"
Undefined/Open Ajna
- Flexible thinker; can see many perspectives
- Not designed to be mentally certain
- Deep wisdom in holding multiple viewpoints without needing a fixed opinion

Not-self pattern: Needing to be sure, needing to have it all figured out mentally.

Gentle experiment:

Practice saying, “I don’t know yet.”
Notice where your body (Strategy + Authority) disagrees with your mind.

3.3 Throat Center – Expression & Manifestation

Role: The Throat is the center of communication and action. It’s how energy in the chart is expressed into the world.

Defined Throat
- Consistent way of speaking and expressing
- People recognize you for how you talk or what you say
- May feel pressure to always have something to say
Undefined/Open Throat
- Voice and expression change depending on who you’re with
- Not meant to force attention; it comes when recognized
- Deep wisdom in using your voice selectively and impactfully

Not-self pattern: Trying to get attention or to be heard at any cost.

Gentle experiment:

Pause before speaking and check: “Is this invited/recognized?”
Let silence be okay. Your voice lands more deeply when it’s timely.

3.4 G Center – Identity, Love & Direction

Role: The G Center holds your sense of identity, love, and life direction.

Defined G Center
- More stable sense of who you are
- Others feel your consistent presence and orientation
- Your direction tends to come from within
Undefined/Open G Center
- Identity and direction feel more fluid and context-based
- Deep sensitivity to environments and relationships
- Not here to “lock in” one identity; here to experience many

Not-self pattern: Obsessing over "Who am I?" or "Where am I going?"; staying in places that feel wrong just to feel secure.

Gentle experiment:

Focus less on who you are and more on where you are.
Ask: “Does this place / group / environment feel good in my body?”

You can explore more nuances here:

3.5 Heart / Ego Center – Willpower & Value

Role: The Heart (also called Ego or Will Center) is about willpower, value, self-worth, and commitments.

Defined Heart
- Consistent access to willpower (when used correctly)
- Not here to work hard all the time, but to use will strategically
- Can make promises and follow through—when aligned
Undefined/Open Heart
- Inconsistent willpower; energy for pushing comes and goes
- Not here to prove anything by effort
- Deep wisdom about value that isn’t based on performance

Not-self pattern: Trying to prove your worth, overpromising, pushing from will instead of alignment.

Gentle experiment:

Before committing, ask: “Am I doing this to prove something?”
Let your Strategy & Authority decide, not your ego.

3.6 Sacral Center – Life Force & Work

Role: The Sacral is pure life force energy: work, creation, sexuality, and sustainable stamina.

Only Generators and Manifesting Generators have this center defined.

Defined Sacral
- Consistent access to life force and work energy—but only for what you love responding to
- Here to respond, not to initiate from the mind
- When aligned, you feel satisfaction and a deep sense of “fullness”
Undefined/Open Sacral
- Not designed for constant go-go-go
- Learn when enough is enough; rest is essential
- Can become deeply wise about sustainable work and energy

Not-self pattern:

Defined: Saying yes from the mind, working in frustration.
Undefined: Pushing past exhaustion to keep up with others.

Gentle experiment:

If you’re a Generator or MG, practice waiting to respond and noticing your gut sounds/reactions.
If you’re Non-Sacral (Projector, Manifestor, Reflector), track what truly drains you vs. restores you.

3.7 Solar Plexus Center – Emotions & Truth Over Time

Role: The Solar Plexus governs emotions, sensitivity, desire, passion, and nervousness. It’s also one of the main authorities in Human Design.

Defined Solar Plexus
- You experience a wave of emotions—highs, lows, and everything between
- There is no true clarity in the now; time brings emotional truth
- Your decisions are about riding the wave instead of reacting at the peak
Undefined/Open Solar Plexus
- Highly sensitive to the emotions of others
- Amplifies emotional energy in your environment
- Deep wisdom around emotional boundaries and what truly belongs to you

Not-self pattern:

Defined: Making impulsive decisions at emotional highs or lows.
Undefined: Avoiding conflict and truth just to keep the peace.

Gentle experiment:

Defined: Sleep on big decisions; notice how clarity changes over time.
Undefined: Ask yourself, “Is this feeling mine or someone else’s?”

3.8 Spleen Center – Intuition & Survival Awareness

Role: The Spleen is about instinct, intuition, body awareness, immunity, and fears. It operates in the now.

Defined Spleen
- Consistent intuitive sense and body awareness
- Can have stable health patterns (though not always “healthy” by default)
- Intuition is quiet but reliable when trusted
Undefined/Open Spleen
- Sensitive to others’ fears and health states
- Tendency to hold onto people/things longer than is healthy
- Potential for deep wisdom around timing, letting go, and bodily signals

Not-self pattern: Staying in unhealthy situations because they feel familiar; ignoring your body’s early warning signals.

Gentle experiment:

Ask: “Does this feel clean and healthy for me—right now?”
Notice those tiny, fleeting intuitive hits before the mind jumps in.

3.9 Root Center – Pressure & Drive

Role: The Root is both a pressure and motor center. It’s about stress, drive, adrenaline, and the pressure to begin or complete things.

Defined Root
- Consistent relationship to pressure; you may thrive on a certain level of stress
- Others can feel rushed around you without you realizing
- Can be productive when pressure is respected, not glorified
Undefined/Open Root
- Strong sensitivity to external stress and deadlines
- Tendency to rush just to get rid of the feeling of pressure
- Potential wisdom about pacing, rest, and relaxed productivity

Not-self pattern: Doing things just to be free of pressure, not because they’re correct for you.

Gentle experiment:

Catch yourself when you think, “I just need to get this over with.”
Slow your pace by 5–10% and see if the world still moves.

4. How to Actually Use This: Centers in Daily Life

Knowing about the centers is helpful—but using them is where your experiment starts.

4.1 Start With Your Defined Centers

Your defined centers are where you’re most consistent.

Ask for each defined center:

How does this show up in my life already?
Where do I naturally operate this way without trying?

These are areas you can usually trust as your baseline, especially when aligned with your Type and Authority (if you’re unsure about those, read: Your Human Design Strategy: Living in Alignment and Your Human Design Authority: The Key to Decision Making).

4.2 Be Gentle With Your Undefined/Open Centers

Your undefined/open centers are where you:

Take in and amplify other people’s energy
Are most vulnerable to conditioning
Have the greatest potential for wisdom

Ask for each open center:

Who or what influences me here the most?
What patterns am I trying to live up to that aren’t really mine?

4.3 One Simple Weekly Practice

Once a week, choose one center and journal:

Is this center defined or undefined/open for me?
How did this energy show up for me this week?
Where did I feel resistance, stress, or pressure here?
What might it look like to move 5% closer to ease in this center?

This is how you slowly decondition and come back to yourself. For more on that process, you can explore: Deconditioning with Human Design: Releasing Not-Self Patterns.

5. FAQ: Human Design Centers

Do more defined centers mean I’m “stronger” or more evolved?

No. Having many defined centers doesn’t make you better; it just means you’re more fixed in how your energy operates. Having more open centers doesn’t make you weaker; it often means you’re more sensitive and adaptable. Both are equally valid.

Is it bad to have a lot of open centers?

Not at all. Open centers can feel vulnerable because you’re taking in so much from the world—but they also hold tremendous wisdom once you learn to recognize what is you and what is not you.

Which center is the most important?

None of them in isolation. Your design is meant to be read as a whole. That said, your Authority (which often comes from a particular center, like the Solar Plexus or Sacral) is key for decision-making. If you’re new, focus on:

Your Type
Your Strategy
Your Authority

You can then use the centers to add nuance. A helpful starting point is: What Is Human Design? Your Complete Guide for Beginners.

What’s the difference between “undefined” and “open” centers?

Technically:

Undefined = white center with one or more gates activated
Open = white center with no gates activated

In everyday language, many people say "open" when they mean any white center. The key idea is: white = receptive and variable.

How do centers relate to Types and Profiles?

Type (Generator, Manifesting Generator, Projector, Manifestor, Reflector) is determined by which motors are connected to the Throat (or not) and whether the Sacral is defined.
Profile is about your role and style in life.

Centers provide the energetic context for how your Type and Profile actually feel day to day. If you’re still grounding these basics, you might like:
