In the Human Design Bodygraph, there are nine centres, each serving distinct purposes and corresponding to different aspects of human experience. These centres can be either defined (coloured in) or undefined (white), indicating whether an individual has consistent energy in that area or is influenced by the energies of others.
Head Centre: This is the centre of mental pressure and inspiration. It governs thoughts, ideas, and questions. The defined Head Centre experiences consistent mental energy, while the undefined may find themselves influenced by external thoughts.
In Human Design, the Head Centre, also referred to as the Crown Centre, plays a significant role in how individuals experience thoughts, inspiration, and mental clarity. The main difference between an open (undefined) Head Centre and a defined Head Centre lies in how one processes mental energy and handles mental pressure.
Open (Undefined) Head Centre
Individuals with an open or undefined Head Centre are influenced by the thoughts and ideas of their environment. They tend to absorb mental energy from others, leading to an openness to diverse concepts and a variety of perspectives. However, this configuration may also create challenges such as mental overwhelm or confusion, as they can easily pick up and amplify the pressure of others' expectations or thoughts.
Experience Example:
A person with an open Head Centre might find themselves feeling excited and inspired by a compelling idea presented by a friend, only to later feel uncertain or pressured to come up with an equally innovative idea. Since they do not have consistent access to mental energy, they may struggle with making decisions or maintaining a clear sense of self-directed inspiration.
Defined Head Centre
In contrast, individuals with a defined Head Centre possess a consistent mental energy that allows them to generate ideas and insights independently. They typically have their own thought processes and are less easily swayed by the mental pressures of others. This provides them with clarity and confidence in their mental expressions.
Experience Example:
A person with a defined Head Centre will often notice that they have a reliable source of inspiration or insight. They may come up with original ideas that they feel confident about sharing, regardless of the surrounding influences. Their thought processes are often steady, and they can engage with the world intellectually without feeling the need to constantly cater to external pressures.
Population Percentages
According to statistical analyses based on Human Design, approximately 70% of the population has an open or undefined Head Centre, which reflects a broad spectrum of mental influences. In contrast, around 30% of people have a defined Head Centre, indicating a smaller group with consistent mental processing capabilities.
In summary, the distinction between open and defined Head Centres affects how individuals approach thought and inspiration, influencing their capacity to manage mental pressure and clarity in decision-making.
Ajna Centre: Located below the Head Centre, it deals with conceptualisation, understanding, and mental clarity. A defined Ajna has a fixed way of thinking, whereas an undefined Ajna can take in various perspectives but may struggle with mental certainty.
In Human Design, the Ajna Center is central to how individuals process mental concepts, beliefs, and ideas. It governs the way we think, analyze information, and form opinions. The distinction between an open (undefined) Ajna Center and a defined Ajna Center primarily relates to how one experiences and manages mental clarity, certainty, and the pressure of mental energy. Those with a defined Ajna Center often possess a consistent way of thinking and can provide clarity and information to others. In contrast, individuals with an open Ajna Center may be more versatile in their thinking but may also experience mental pressure from external sources, leading to fluctuations in their mental clarity and beliefs.
Open (Undefined) Ajna Centre
Individuals with an open or undefined Ajna Center are influenced by the mental energy and concepts present in their environment. They tend to absorb thoughts and ideas from others, fostering receptivity to a wide range of perspectives. This openness can lead to a rich understanding of various viewpoints. However, it may also present challenges such as mental overwhelm or confusion, as they can easily pick up and amplify the pressure of others' expectations and beliefs.
Experience Example:
A person with an open Ajna Center in Human Design may initially feel excited and inspired by a compelling idea shared by a friend, yet later experience uncertainty or pressure to produce an equally innovative concept. Lacking consistent access to mental clarity, they may find themselves struggling to make decisions or maintain a clear sense of self-directed inspiration. This openness can lead to fluctuating perspectives and challenges in aligning thoughts with their personal beliefs. Instead of holding on to fixed ideas, they might benefit from embracing different viewpoints while cultivating a sense of inner authority over their mental processes.
Defined Ajna Centre
In contrast, individuals with a defined Ajna Center possess a consistent mental energy that allows them to generate ideas and insights independently. They typically have their own thought processes and are less easily swayed by the mental pressures of others. This configuration provides them with clarity and confidence in their mental expressions, leading to a strong sense of certainty in their beliefs and perspectives. Their ability to mentally process information can enhance their understanding and retention of knowledge, enabling them to form clear insights that they can articulate effectively.
Experience Example:
A defined Ajna Center provides mental clarity and original insights. Individuals can share their concepts confidently, unaffected by outside influences. Their thought processes are steady, allowing for intellectual engagement without pressure to conform. This internal perspective helps them process information authentically.
Population Percentages
According to statistical analyses based on Human Design, approximately 65% of the population has an open or undefined Ajna Center, reflecting a broad spectrum of mental influences and varying perspectives on understanding and processing information. In contrast, around 35% of people have a defined Ajna Center, indicating a smaller group that possesses consistent mental clarity and a more reliable way of conceptualizing and processing thoughts.
The difference between open and defined Ajna Centers in Human Design affects thought processing. Those with a defined Ajna Center have consistent thinking, mental clarity, and reliable decision-making, managing mental pressure effectively. In contrast, those with an open Ajna Center are adaptable but may struggle with external influences, leading to challenges in mental coherence and reliance on environmental insights. Recognizing this distinction is key to understanding how Ajna Centers shape cognitive experiences and personal dynamics.

Throat Centre: The Throat Centre is central to communication and manifestation. It represents how one expresses themselves and channels energy into action. Defined Throat Centres may have a consistent way of expressing; undefined types might amplify the voices of others.
G Centre: This centre relates to identity, love, and direction in life. It is about one’s sense of self and purpose. A defined G Centre offers a solid sense of identity, whilst an undefined G Centre may feel influenced by others’ identities.
Heart Centre (Ego Centre): The Heart Centre is connected to willpower, material realms, and ego. It governs self-esteem and desire. Those with a defined Heart Centre tend to have consistent motivation, whereas those with an undefined centre may find varying levels of will and self-worth.
Sacral Centre: This is the centre of life force energy and response. It is the source of creativity and reproductive energy. A defined Sacral Centre has reliable energy for work and creation, while an undefined Sacral may be influenced by external energies.
Spleen Centre: The Spleen Centre is about intuition, health, and survival instincts. It provides awareness of the present moment and instinctual responses. Defined Spleen Centres often have a consistent instinctual awareness, while those that are undefined may lack clarity in their instincts.
Solar Plexus Centre: This centre concerns emotional awareness and processing. It governs feelings and emotional energies. Defined Solar Plexus Centres experience consistent emotional waves, while an undefined Solar Plexus may feel overwhelmed by the emotions of others.
Root Centre: Located at the base of the bodygraph, the Root Centre relates to adrenaline, stress, and drive. It provides the stamina to take action. Those with a defined Root Centre experience a consistent sense of pressure to act, while those with an undefined centre might absorb the stresses of their environment.
These centres collectively represent a complex interplay of energies that shape an individual’s experience, environment, and interpersonal dynamics, as articulated by Ra in the Human Design system.
In Human Design, the concepts of open and defined centres refer to how energy operates within an individual's body graph, which is a visual representation of their unique energetic makeup.
A defined centre is one that is coloured in on the body graph, indicating that the person consistently experiences and expresses the energy associated with that centre. Defined centres are associated with specific traits and characteristics, suggesting that the individual has a reliable and stable way of processing energy related to those centres. For instance, a defined Heart Centre may indicate a person with a strong sense of willpower and self-worth.
An open centre, on the other hand, is white and represents areas where the individual does not have consistent access to that energy. This openness means that the person is more susceptible to external influences and can easily absorb and reflect the energy, emotions, or traits emanating from others. While open centres can lead to greater flexibility and adaptability, they may also result in challenges such as inconsistency in identity or emotional fluctuations.
Understanding the balance between defined and open centres can offer insights into how a person interacts with the world, their inherent strengths, and potential areas for growth.
