Defined vs. open centers: energy in human design

Do you know that feeling of being completely exhausted after a long day at work—even though you didn’t really do “anything special”? Or that you suddenly come alive in some groups, while in others you can barely concentrate? The Human Design System offers a fascinating explanation: the so-called Human Design Centers. They describe how we receive, process, and transmit energy—and why the same environment affects different people in completely different ways. This article explains what defined centers and open centers are, what role conditioning plays in this, and how this knowledge can help you understand yourself better—without any esoteric jargon.

What Are Human Design Centers? An Overview

The Human Design System was developed in the late 1980s by Ra Uru Hu and combines elements from quantum physics, Kabbalah, the I Ching, astrology, and the Hindu chakra system into a unique personality model. At the heart of this system are nine energy centers, which are represented as geometric shapes in the so-called Bodygraph.

These nine Human Design centers resemble the seven classical chakras of the Hindu tradition in their arrangement, but are not identical to them. While the chakra system recognizes seven main energy points, Human Design works with nine centers, each representing specific biological, neurological, and psychological functions. The centers are called: Root, Sacral, Solar Plexus, Spleen, Heart (also called Ego or Will), G-Center (Identity), Throat, Ajna, and Head.

Each of these centers can be either defined (colored) or open (white) in your personal Bodygraph—and it is precisely this difference that is crucial for understanding your energy, your strengths, and your so-called non-self themes.

Defined Centers: Your Reliable Source of Energy

A defined center is colored in the body graph—usually in one of nine possible colors. This means: This center has a stable, consistent energy quality. It functions reliably, regardless of where you are, who you’re with, or what your environment is like at the moment.

People with a defined heart center, for example, have steady access to willpower and motivation—not because they are exceptionally disciplined, but because their energy simply flows constantly in this area. The same applies to other centers: A defined sacral center provides robust life energy, and a defined throat center offers consistent expressiveness.

It is important to understand: Defined centers are no guarantee of perfection. However, they radiate their energy outward—and this influences the people around you. Those close to you absorb this energy and may even amplify it. The Human Design System calls this process conditioning—more on that in a moment.

Open Centers: Receivers, Mirrors, and Learning Fields

Open centers are shown in white on the body graph. This does not mean that there is no energy there at all—on the contrary. Open centers are highly receptive: they absorb energy from the environment, amplify it, and release it again. This makes them an enormous learning field, but also a potential source of confusion and exhaustion.

Imagine an open Sacral Center: People with this configuration do not have a steady, self-generated life energy. However, when they are around people with a defined Sacral Center, they can absorb their energy—and suddenly feel more alive and active than they have in a long time. The problem arises when they confuse this state with their natural normal state and try to function permanently at this energy level.

Herein lies one of the central insights of the Human Design System: Open centers are neither weaknesses nor deficits. They enable a deep wisdom regarding the area they represent—precisely because they come to know so many different forms of expression of it. A person with an open head center, for example, experiences the thinking styles and mental patterns of a wide variety of people—and can thereby develop an exceptionally broad understanding of mental processes.

Conditioning: When External Energy Becomes Your Own

Conditioning is one of the central concepts in the Human Design System—and at the same time one of the most frequently misunderstood. It refers to the process through which open centers absorb, amplify, and internalize external energy—until we can no longer distinguish between what is “us” and what comes from outside.

This may sound abstract at first, but it can be experienced very concretely in everyday life. Let’s take the open Heart Center as an example: People with this open center do not have consistent access to willpower and self-esteem from within themselves. When they are near someone with a defined Heart Center, they suddenly feel confident, motivated, and strong. The conditioning arises when they begin to make promises, start projects, or commit to things—believing that this energy belongs to them permanently. When the other person leaves the room, the energy is gone too. And the promises made cannot be kept.

Psychological research describes similar patterns under the term “emotional contagion.” As Hatfield, Cacioppo, and Rapson demonstrated as early as 1993 in their seminal work, people transmit emotions and energy states through unconscious mimicry and synchronization—a process closely related to what Human Design refers to as conditioning.

Key message: Open centers as a source of wisdom Open centers are not weaknesses - they are learning fields. Those who understand which energy belongs to them and which they are only temporarily absorbing gain a deep form of self-knowledge. The Human Design System calls this process „deconditioning“ - and according to Ra Uru Hu, it takes about seven years because every cell in the body has to realign itself.

The Nine Centers and Their Non-Self Themes

Every open center has a so-called non-self theme—a characteristic question or behavioral pattern that arises when we confuse the absorbed, conditioned energy with our own. These non-self themes are not moral judgments, but rather indications of where we have strayed from ourselves.

• Head Center (open): “Do I have to answer this question?” – People with an open head often feel pressured to think about things that don’t really interest them.
• Ajna Center (open): “I’m not sure, but…” – The non-self theme is feigning certainty in order to fit in.
• Throat Center (open): Speaking or acting to get attention—instead of waiting until you’re truly invited.
• G-Center (open): Constant search for identity and direction – “Who am I, really?”
• Heart Center (open): Having to prove oneself, making commitments one cannot keep.
• Spleen Center (open): Clinging to things, situations, or relationships that don’t feel right—out of fear.
• Solar Plexus (open): Avoiding conflicts so as not to hurt others—at the expense of one’s own truth.
• Sacral Center (open): Not knowing when you’ve done enough—chronic exhaustion from overwork.
• Root Center (open): Getting things done to relieve pressure—instead of acting on a genuine impulse.

Recognizing these patterns is the first step toward what is known as deconditioning—the process of freeing oneself from inherited energies and returning to one’s own nature.

Comparison with the Chakra System: Similarities and Differences

Since the Human Design System is based, among other things, on the Hindu chakra system, a brief comparison is worthwhile. The classical chakra system recognizes seven main energy centers along the spine: root, sacral, solar plexus, heart, throat, brow (Ajna), and crown chakras. In the yogic tradition, these centers are associated with specific physical organs, emotional qualities, and spiritual attributes.

Human Design adopts this basic idea but expands it to nine centers, adding two: the G-Center (linked to identity, love, and direction) and the Spleen Center (associated with intuition, the immune system, and survival instinct). Furthermore, Human Design shifts the focus from a spiritual hierarchy of chakras to a non-hierarchical network: no center is more important than another. All nine work together.

Another key difference lies in the concept of openness: In the chakra system, “blocked” chakras are viewed as a problem that must be healed or opened. In the Human Design system, however, open centers are structurally neutral—they are simply different from defined centers, neither worse nor better. This perspective aligns well with modern psychological approaches that do not pathologize individual differences but recognize them as variations of human experience.

What Research Says About Energy Transmission

Human Design is not a scientifically validated system in the classical sense—it is important to state this honestly. There are no randomized studies confirming the Body Graph as a measuring instrument. Nevertheless, there are interesting points of contact with established psychological and neuroscientific research.

The aforementioned research on emotional contagion (Hatfield et al., 1993) shows that people unconsciously adopt emotions and energy states from one another—a phenomenon that is well documented in social neuroscience. Mirror neurons, discovered by Giacomo Rizzolatti and his team in the 1990s, are considered a possible neurobiological basis for empathy and social resonance—processes that resemble what Human Design describes as the absorption of energy through open centers.

Research on highly sensitive personalities is also relevant here: In her groundbreaking work (1996), Elaine Aron showed that approximately 15–20 percent of the population reacts significantly more sensitively to environmental stimuli than others. These people process sensory and social information more deeply—which functionally resembles what Human Design would describe as “many open centers.” Whether this is the same phenomenon cannot be said—but the direction gives pause for thought.

Kristin Neff, the pioneer of self-compassion research, demonstrated in 2003 that an understanding approach to one’s own limits and idiosyncrasies—that is, the opposite of self-judgment—is central to psychological well-being. This is precisely what the Human Design System offers its users: a framework for approaching oneself with curious acceptance, rather than criticizing oneself for differences in energy and perception.

How to Use Your Open Centers as Strengths

The practical value of the Human Design System lies less in blind faith in the body graph and more in the reflection it inspires. Once you know which of your centers are open, you can begin to view certain patterns in your life through a different lens.

Step 1: Get to know your body graph

Create your free body graph on one of the various online platforms available. You’ll need your exact date of birth, time of birth, and place of birth. The open (white) and defined (colored) centers are immediately recognizable.

Step 2: Observe your non-self themes

Look at the list of open centers in your chart and read up on which non-self theme is associated with each one. Do you recognize this pattern in your life? Don’t jump to conclusions right away—just observe at first, with curiosity and without judgment.

Step 3: Ask the question

Human Design provides a liberating question for each open center. For the open Sacral Center, for example, it is: “Have I done enough?” For the open Heart Center: “Do I have something to prove?” These questions help break conditioned patterns—not through willpower, but through awareness.

Step 4: Consciously perceive energy

If you feel unusually energetic or unusually exhausted in a certain environment: Ask yourself whether this state comes from you or from the environment. Over time, you will develop a sense of what belongs to you—and what you are merely carrying temporarily.

Deconditioning: The Path Back to Yourself

The concept of deconditioning is perhaps the most profound aspect of the Human Design System. It describes the process through which we learn to distinguish between our own energy and the energy we have adopted—and gradually find our way back to our authentic nature.

This process is not a quick fix. Ra Uru Hu spoke of a period of about seven years, because conditioning is stored not only on a mental level but also on a cellular level. That sounds like a long time—but interestingly, it aligns with neuroscientific findings on neuroplasticity: Deeply ingrained patterns of thought and behavior do not change overnight, but through persistent, repeated new experiences.

In practice, deconditioning means above all: slowing down. Pausing before committing. Noticing how you feel—before acting. Asking yourself whether a desire, a fear, or a belief truly comes from within you.

This is less of an esoteric concept and more a form of mindfulness applied through the lens of one’s own energy profile. And research—including Jon Kabat-Zinn’s work since the 1970s—has clearly shown that mindfulness demonstrably changes the way we react to ourselves and the world.

Human Design in Everyday Life: Small Steps with a Big Impact

It doesn’t have to be a complete life overhaul right away. Using the Human Design System as a tool for self-reflection can be very effective even in small, everyday situations.

For example, if you know that your Solar Plexus is open—the center for emotions—you might notice that during charged conversations, you experience other people’s emotions very intensely. Instead of getting carried away in these moments, you can take a step back internally and ask yourself: “Is this my feeling—or did I just pick it up?”

Or you might realize that your root center is open—the center for handling pressure and stress. Then you may recognize why you immediately feel stressed yourself when in the company of stressed people. This knowledge allows you to interact more mindfully with your surroundings—and to schedule breaks for recovery, not as a weakness, but as a structural necessity.

Ultimately, when viewed objectively, Human Design is a framework of invitation: an invitation to encounter yourself with more curiosity, more patience, and more compassion. And that is an attitude which—as psychology is convinced—enables genuine change.

What does it mean if almost all my centers are open?

People with many open centers are called reflectors in the Human Design System - they have all nine centers open. This does not mean that they are weak or lacking in energy. On the contrary, they are exceptionally sensitive to their surroundings and can develop deep wisdom about almost all areas of life. The challenge lies in learning which energy belongs to them and which does not. Regular periods of retreat and a conscious environment are particularly important for them.

Can my body graph change over the course of my life?

No - according to the Human Design System, the body graph is fixed at birth and remains constant throughout life. What can change is how you deal with it: Through the process of deconditioning, you learn to use your defined and open centers more consciously and let go of conditioned patterns. The map remains the same - but the travelers become more experienced.

Is Human Design scientifically proven?

Human Design is not a scientifically validated system in the classical sense. There are no controlled studies that confirm the body graph as a diagnostic tool. Nevertheless, there are interesting overlaps with psychological research - for example on emotional contagion, high sensitivity or mindfulness practice. Human Design can be usefully employed as a framework for reflection and a tool for self-knowledge, but should not be misunderstood as a medical or therapeutic instrument.

How do defined and open centers differ in everyday life?

A defined center functions constantly and independently of its surroundings - it emits its energy evenly. An open center, on the other hand, absorbs energy from its surroundings, amplifies it and releases it again. This means that people with many open centers can flourish enormously in the right company, but also need more rest and distance in order to regulate themselves. Defined centers lend reliability and stability - open centers lend adaptability and depth.

What are non-self issues and how do I recognize them in my life?

Non-self issues are characteristic patterns of thought and behavior that arise when open centers treat conditioned energy (i.e. energy taken from the outside) as their own. A typical example: If you have an open heart center, you might constantly put pressure on yourself to prove something - even though this pressure does not come from your own being. The best way to recognize such patterns is through calm self-observation: When do you not feel like yourself? When do you act out of fear, pressure or the desire for recognition - instead of out of genuine impulse?

How do I get started with human design if I'm new to the subject?

The easiest way to get started is to create your body graph online for free - all you need is your exact date, time and place of birth. First, just look at which centers are open and which are defined. Read up on which non-self theme is connected to your open centers - and observe whether you recognize this pattern in your everyday life. You don't have to change anything immediately: Awareness is the first and most important step.

Understanding defined and open centers in Human Design can be deeply liberating: it allows you to see yourself in a new light. Not as someone who “feels too much” or “has too little energy,” but as someone with a very specific energy structure that follows its own inner logic. The concepts of conditioning and non-self themes offer no excuses, but rather points of insight—moments in which you can encounter yourself more honestly.

And that, ultimately, is the core of any meaningful personal development: not becoming the perfect version of yourself, but the authentic one.

Your action step for today: Create your body graph and take a close look at an open center. Read the corresponding non-self theme—and write down three situations from your life in which you recognize this pattern. No judgment, no solutions. Just honest observation. That is the beginning of deconditioning.
