The nine Energy Centers in the Human Design Bodygraph are fascinating components that offer deep insights into our energetic makeup and how we interact with the world. These Centers are analogous to the chakras in spiritual traditions but with specific functionalities and themes in Human Design. Each Center uniquely influences how we process energy, emotions, and information, influencing everything from our thought processes to our health and communication.

Each of the nine Energy Centers in the Bodygraph can be defined or undefined, which significantly influences your personality, how you interact with the world, and how you process energy. The state of these Centers—whether colored in (defined) or white (undefined)—provides insights into your consistent traits, potential vulnerabilities, and areas for growth.

The Impact of Defined and Undefined Centers

The interaction between defined and undefined Centers in your Bodygraph shapes your individuality and how you connect with others. For instance, in relationships, people often feel drawn to others with their undefined Centers defined, which can create a sense of balance or complementarity.

Understanding whether a Center is defined or undefined in your chart can offer profound insights into your behavior, motivations, and interactions with the world. It helps you recognize where you can stand firm in your energy and where there is room to grow and learn from the people and environment around you. This awareness is key to navigating life with more ease and authenticity, allowing you to honor both your strengths and areas of potential development.

Defined Centers

A Center is considered defined when it is colored in on the Bodygraph. This coloring indicates a consistent flow of energy through that Center, which impacts how you express specific aspects of your nature. Defined Centers represent areas of strength, consistency, and reliability in your personality and energetic makeup. The characteristics associated with a defined Center are likely to be prominent in your behavior and self-expression and remain relatively stable over time.

Key Characteristics of Defined Centers:

  • Consistency: The energy and traits of defined Centers are consistent, forming a core part of your identity that you can access regularly.
  • Reliability: Others may see you as reliable or predictable in the areas represented by your defined Centers.
  • Strength: Defined Centers are sources of strength and can be areas where you have the potential to teach or guide others.
  • Influence: While defined Centers are less susceptible to external influences in their specific areas, they can influence others, especially those with the corresponding Centers undefined.

Undefined Centers

An undefined Center appears white in the Bodygraph and represents an area where you do not have a fixed or consistent way of processing or expressing that Center’s energy. Undefined Centers are not weaknesses; instead, they are areas of flexibility, learning, and wisdom. They indicate the potential for growth and the capacity to understand and empathize with a wide range of experiences in that aspect of life.

Key Characteristics of Undefined Centers:

  • Openness: Undefined Centers are open to external influences, making you receptive to different energies and perspectives in these areas.
  • Flexibility: You may find that you can adapt easily to the areas represented by undefined Centers, taking on different roles or understanding various viewpoints.
  • Learning and Wisdom: Undefined Centers are where you have the potential to learn the most about yourself and others. Over time, you can develop wisdom in these areas based on your experiences and reflections.
  • Empathy: An undefined Center can make you empathetic to how others experience that Center’s energy, as you can resonate with a broad spectrum of related expressions and challenges.

Each Energy Center has a Purpose

Pressure Centers: Head and Root

The Head and Root Centers apply pressure to the centers they connect to.

The Head Center puts pressure on the Ajna Center.

  • Inspiration to Conceptualization: The Crown’s pressure on the Ajna Center is a push to conceptualize, analyze, and give form to the thoughts and questions that arise in the Crown, which can lead to constant mental activity as the Ajna seeks to process and make sense of these inspirations.
  • Decision-Making: Pressure can influence how we make decisions. With the Crown generating constant questions and the Ajna trying to rationalize them, individuals might overthink or be stuck in analysis paralysis if not managed properly.
  • Mental Pressure: This can often feel like internal pressure to figure things out, answer the big questions in life, or continuously seek knowledge and understanding. This drive can lead to profound insights and mental exhaustion if not balanced with rest and disengagement from mental activities.

The Root Center puts pressure on the Spleen, Sacral, and Emotional Solar Plexus Centers.

  • Influence on the Spleen Center: When the Root Center exerts pressure on the Spleen Center, it’s about the urgency and instinct to survive and thrive. The Spleen, associated with intuition, health, and time, feels the push to make decisions that protect and promote well-being. This connection can lead to quick, in-the-moment actions aimed at ensuring survival and maintaining health, but it might also cause stress related to health and well-being if not managed wisely.
  • Impact on the Sacral Center: The Root’s pressure on the Sacral Center, the center for work, sexuality, and life force, energizes individuals to take action, create, work, and engage with life’s demands. This dynamic can inspire great productivity and the capacity to respond to life’s challenges with resilience and energy. However, for those with an undefined Sacral Center, this pressure can lead to overwork or an unhealthy sense of urgency to keep up with perceived demands.
  • Effect on the Solar Plexus: The Root Center indirectly influences the Solar Plexus, the emotional center, through other centers like the Sacral and Spleen. This influence can create a sense of pressure to resolve emotional issues or to move through emotional processes more quickly than might be natural. It underscores the importance of pacing oneself and allowing emotional clarity to emerge in its own time rather than rushing decisions or actions based on transient feelings.

Awareness Centers: Ajna, Emotional Solar Plexus, Spleen

Spleen Center (Intuition and Instinctual Awareness)

The Spleen Center, the oldest awareness center in evolutionary terms, is associated with primal instincts, intuition, and the body’s innate immune response. It’s fundamentally linked to survival, providing spontaneous, in-the-moment awareness to guide us away from danger and towards health and vitality. This center operates on a tactile level, giving us a visceral, gut-level sense of what is safe and what isn’t.

  • Defined Spleen Center: Individuals with a defined Spleen Center have consistent access to their intuition and instincts. They can rely on their spontaneous feelings and hunches to make decisions and navigate their environment.
  • Undefined Spleen Center: Those with an undefined Spleen might experience inconsistent or less reliable instincts. They can be more sensitive to their environment and the health and well-being of others, absorbing and amplifying these signals.

Ajna Center (Conceptual Awareness)

The Ajna Center is concerned with mental processes, including thinking, analyzing, and conceptualizing. It’s where we process our thoughts and beliefs, making sense of the information we receive from the world around us. The Ajna Center is deeply involved in forming our viewpoints and how we rationalize our experiences and ideas.

  • Defined Ajna Center: A defined Ajna suggests a consistent way of thinking and processing information. Individuals with this configuration can trust their internal processes to make decisions and form opinions.
  • Undefined Ajna Center: An undefined Ajna indicates a more flexible and adaptable mindset, capable of seeing multiple sides of an issue. However, this can also mean being influenced by the prevailing opinions or information presented by others.

Emotional Solar Plexus Center (Emotional Awareness)

The Solar Plexus Center is the seat of our emotions and moods, governing our emotional intelligence and awareness. It plays a significant role in how we feel and experience life, coloring our interactions and decision-making processes with an emotional hue. This center is associated with emotional waves, varying from high to low, reflecting the dynamic nature of our emotional experiences.

  • Defined Solar Plexus Center: Those with a defined Solar Plexus experience consistent emotional waves and have access to emotional wisdom through these cycles. Their emotional state deeply influences their decision-making process, and they benefit from waiting for emotional clarity before acting.
  • Undefined Solar Plexus Center: An undefined Solar Plexus means experiencing emotions magnified, absorbing, and amplifying the emotions of others. It offers the potential for deep empathy and understanding of emotional nuances, though it may lead to challenges distinguishing personal emotions from those picked up by others.

Expression Centers: Throat and Will/Ego

Throat Center (Communication and Manifestation)

The Throat Center stands at a unique crossroads within the Bodygraph, serving as the hub for all energy aiming to be expressed outwardly. It is the center of communication, speaking, listening, and action. In Human Design, the Throat Center is the only center directly connected to all the other centers, highlighting its role as the primary outlet for manifesting thoughts, feelings, and energies into the world.

  • Defined Throat Center: Individuals with a defined Throat Center have a consistent way of expressing themselves. They can reliably manifest their thoughts and ideas into speech and action. Their communication style is stable, and they often find it easier to vocalize their thoughts and feelings. This definition also indicates a natural ability to attract attention and articulate what needs to be expressed.
  • Undefined Throat Center: People with an undefined Throat Center may experience variability in their expression and manifestation. They could be highly adaptable in how they communicate, often reflecting or amplifying the communication styles of those around them. While this makes them versatile and receptive communicators, it also leads to challenges in consistently expressing their true selves or feeling heard.

Will Center (Heart or Ego Center)

The Will Center, also known as the Heart or Ego Center, is the center of willpower, self-esteem, and material success. It governs our capacity to make promises, set goals, and follow through with commitments. This center is closely related to our sense of worth and the drive to prove ourselves, both to ourselves and others.

  • Defined Will Center: A defined Will Center endows an individual with consistent access to willpower and a strong sense of self-worth. They have the inner strength to make promises and meet their commitments. This consistent access to willpower can contribute to a robust understanding of self-esteem and the ability to achieve material and social success. However, these individuals must remember the value of rest, as constant exertion can lead to burnout.
  • Undefined Will Center: Those with an undefined Will Center might find their willpower and sense of self-worth fluctuating. They may struggle with making and keeping promises or setting boundaries, often because they feel a need to prove their worth. Learning to recognize their inherent value without tying it to accomplishments or the approval of others can be a significant growth path for individuals with this configuration.


Motor Centers: Will/Ego, Emotional Solar Plexus, Sacral, and Root

These centers are the powerhouses of our energy system, driving us to act, create, and respond to life’s challenges and opportunities. There are four Motor Centers: the Will (or Ego) Center, the Emotional Solar Plexus, the Sacral Center, and the Root Center. Each has its unique way of generating and expressing energy.

The Will Center gives us stamina and value-driven purpose; the Emotional Solar Plexus offers emotional depth and wisdom; the Sacral Center fuels our capacity to work and create; and the Root Center pushes us to change and grow.

Will/Ego Center

The Will Center, also known as the Ego Center, is associated with willpower, determination, and the material aspects of life. It’s the center of value and worth in terms of self-esteem and material resources. When activated, it provides a steady and strong energy to persevere, make commitments, and follow through. It’s about having the will to act and the strength to sustain those actions over time.

Emotional Solar Plexus

The Emotional Solar Plexus is the center for emotional energy and awareness. It generates deep emotional waves that can influence the person who has this center defined and those around them. A powerful motor can drive decisions and actions based on emotional clarity and intelligence. When defined, this center suggests that waiting for emotional waves to pass before making significant decisions is crucial, as clarity often comes with time.

Sacral Center

The Sacral Center is the center of life force, sexuality, and work capacity. It’s considered the most powerful motor for generating and sustaining energy for doing, creating, and working. People with a defined Sacral Center have access to a consistent and renewable energy source, making them capable of enduring work and productivity. This center often differentiates Generators (and Manifesting Generators) in the Human Design system, marking them as the “builders” of the world.

Root Center

The Root Center is the center of adrenaline and stress, providing the pressure to move, act, and change. It’s a motor of transformation, pushing us to evolve and adapt. The energy from the Root Center is pulsing and cyclical, creating bursts of energy to get things done. It operates under pressure, motivating action to relieve tension or stress. This center can drive us to achieve and accomplish, but it requires awareness to manage its pressure healthily.

Direction Centers: Head, G Center, and Will/Ego

The Head | Crown Center—Consciousness Direction—is pivotal in guiding individual and collective consciousness. It acts as a beacon, leading our thoughts and inspirations towards higher awareness and understanding.

The G Center—Purpose and Love Direction—is central to finding our way in life and is the navigational heart of our purpose and love. It is instrumental in steering us towards our true path and connecting us with others meaningfully.

The Will | Ego | Heart Center—Material Direction—offers direction in the material realm, grounding our ambitions and willpower in the tangible world. It’s about giving shape and form to our material aspirations and endeavors.
