An awareness Center and a very important hub for transforming cognitive comprehension and processing. The Design Crystal of the Human is located in the Ajna Center as are the hypothalamus, pituitary, and other autonomic nervous system structures. Because the Ajna Center along with the Head Center function to help us interpret information, we often make decisions based on this Center when it is only an interpreter and, therefore, should never be given this power. Someone with a Defined Ajna Center is not influenced by others' presence but has his/her own preferences and predispositions; someone with an Undefined Ajna Center has a very flexible thinking process that is open to all possibilities.

An awareness Center responsible for our immune functioning and well being in the world. It carries instinct, intuition, and taste which give us information for processing regarding what is healthy for our survival or not. A Defined Splenic Center operates in the present moment with a gentle non-verbal sense of what is healthy and good for us or not. If you have a Defined Splenic Center you can feel good and have the capacity to maintain that good feeling even when others around you do not feel good. If you have a Defined Splenic Center you are here to act in the Now and to be spontaneous since you know in the moment what is healthy and/or unhealthy for you. If you have an Undefined Splenic Center you are highly sensitive to others' and to their feelings. The challenge is for you to know what your own vibration is and what your own experiences are and to not take on the feelings or vibrations of others. Also, avoid spontaneity since you are better off following your strategy and waiting for clarity from there.

An awareness Center and also a Motor/Fuel Center operates in a wave and has impact on all people, regardless of Definition, because of the nature of human consciousness and human nature at this time in our evolution. If you have a Defined Solar Plexus Center you have an awareness center that operates over time and therefore, you are here to wait for the emotional wave to pass before making any decisions or taking any action. It is also important to recognize that emotional clarity only comes over time and that the wave nature of emotions is physiological and not really emotional. At night when we sleep, we lose this center and thus, have a new emotional perspective the next day. If you have an emotional solar plexus definition, always sleep on things before making a decision or taking action. If you have an Undefined Solar Plexus, you are vulnerable to the moods and feelings of others and it is important to note that you may be expressing an emotion that is not yours. It is important to wait out all feelings to gain clarity regardless of definition for this reason.

As noted above, the Solar Plexus Center is both an awareness and a motor/fuel center. It operates over time and thus, as a center that functions as a motor/fuel if you have it defined you must be especially cautious to take time to wait for clarity through the waves of energy that activate this energy center. If you have this Center undefined, you need to be clear that you are not acting as a result of someone else's emotional energy activations.

The Center that controls much of our biology and that creates Pressure and Fuel for survival on the material plane, i.e., in the physical form in the world. A Defined Heart Center creates a powerful force of will and energy that wants its survival known and preserved. If you have a Defined Heart Center you like to be in control of your own life and resources. You also know your own value albeit at times inflated. If you have an Undefined Heart Center you may not recognize your own worth and may not stand up for it. Also, with an Undefined Heart Center, making promises creates pressure on you that is not healthy.

The Sacral Center is the primary source of energy within us and is the empowerment field of life itself. Within the Sacral Center is the genetic imperative for reproduction, intimacy, and nurturing of the species. Within this Center is the Design Crystal of Mammals. There is, thus, an intimate relationship between this Center and the Ajna Center in transforming life force responses to our human cognitive experience and making sense of it. The Sacral Center is a Motor/Fuel Center and when Defined makes someone a Generator. If you have a Defined Sacral Center you are someone who responds to things with a sense of your non-verbal affirmation in your "gut." Words do not exist in this Center, only an internal response with a non-language sound. It is only when the response is translated via the Ajna and Throat Center that words identify it. Thus, if you have a Defined Sacral Center it is important for you to know your non-verbal responses and to wait for them before expending any energy. Someone with a Defined Sacral Center is a Generator or if a Motor reaches the Throat Center, a Manifesting Generator. If you have an undefined Sacral Center you are living with your non-verbal responses unfiltered and open. You may experience frustration because you are so open to the collective life force energies that are present around you and you cannot easily translate them into your own non-verbal response patterns. If you have an undefined Sacral Center follow your strategy to be healthy.

The Root Center is a Motor/Fuel Center as well as the Pressure Center of life itself. The Root energies set in motion the way your body and mind feel pressure and process the movement of energy through you. If you have the Root Center Defined, you feel the strong pressure of this Motor and you process activities in your life in line with your activated Gates. Because the Root Center is a Pressure Center, it drives you and pushes for involvement. If you have an Undefined Root Center you do not have the pressure within you that creates stress so you may be taking stress on from others and feel pressure that is not yours. Living your strategy prevents depression that comes from unnecessary pressure in all circumstances.

A Center of pressure to comprehend and make sense of things in the universe. It is the Center of inspiration. The Personality Crystal of the Human is located in the Head Center. When Defined the Head Center creates a mental pressure to grasp and to understand things in certain ways. When Undefined the Head Center is open to ideas and inspiration coming from all directions.

See the Description in the Motor/Fuel Center section.

The Center of Manifestation and communication. With 11 Gates as possibilities from the Throat Center it is a very important center regardless of whether it is defined or not. If Defined, the Gate activations determine the way in which you speak since the connections to the Throat Center give the voice its expression. If the Throat Center is connected (defined) to a Motor/Fuel Center it becomes a center which can initiate action and results in the person being a Manifestor or a Manifesting Generator. Someone with a defined Throat Center can always speak. Someone with an undefined Throat Center feels pressure to communicate but does not have the capacity to initiate speech and communication. They can, however, speak with the voice of those around them. For them, the pressures on the Throat Center lead them to feel constantly under pressure to speak and it creates anxiety for them. Knowing that they are here to live a strategy and to wait for an opening congruent with that strategy.

The Center that contains the Magnetic Monopole that holds us together in our identity. The eight leading gates in this Center set the roles for the way humans orient themselves in life. A Defined G Center shows the kind of direction and sense for where you are heading in this life. It gives one a sense of a reliable self-identity in terms of this definition. An Undefined G Center allows you to remain open to moving in many directions in life and in being swayed by those around you. If you have an undefined G Center who you are with and where you are in terms of your comfort tells you if you are moving in the right direction.

Someone who has a channel defined that connects from one of the Motor/Fuel Centers to the Throat Center, the Center of Manifestation. Manifestors can initiate action and both like to inform others of their intentions to act and like to be informed before others take action. (8.0% of the population are Manifestors).

Someone who has the Sacral Center defined but no Motor/Fuel Center reaches the Throat Center either directly or indirectly. The Sacral Center is a response center. Thus, a Generator likes to respond to others and feels at ease when waiting for others to elicit a response through verbal or non-verbal questioning or perception of their non-verbal responses. Often Generators feel a "gut" sense of a "yes" ("ah huh"), or a "no" ("un un"). Generators feel frustration when not asked to respond and their strategy must be one of receptivity to respond. Because they wait to respond, they are often frustrated by not being asked. (36.8% of the population are Generators).

Someone who has the Sacral Center defined and who also has a Motor/Fuel Center (which may be the Sacral Center) connected directly or indirectly to the Throat Center. The Manifesting Generator (MG) combines the characteristics of the Generator as a primary strategy and of the Manifestor as a secondary and important step in their process. The MG must wait as a Generator for a response to a stimuli, but then once the response is elicited, the MG then must begin the manifestation process of imaging the action and then must remain constantly vigilant and attentive to the internal responses which give feedback as to whether the action is "correct" or not. The MG must be constantly open to revising their responses and actions. Once a path is set, however, the MG must inform others and be informed in order to prevent frustration and anger. (33.5% of the population are Manifesting Generators).

Someone whose body graph has definition (a connection between at least two centers) but the definition is other than sacral and no motor/fuel center reaches the Throat Center for manifestation. The Projector cannot respond unless some additional connections are made, so the projector must be recognized and invited to contribute the perceptions that are internally clear. The projector presents to others a screen upon which to see a clear energy and thus the projector must wait until others are able to allow that projection to be perceived. (20.9% of the population are Projectors).

Someone who has no definition anywhere in the body graph. A reflector is someone who is open totally to input from outside and who moves with the energies flowing through them. At times with the presence of others in the auric field, a reflector gains definition because of the "hook ups" with the other person. It is, thus, through experiences in the world and with others that reflectors experience themselves and know who they are. (0.9% of the population are Reflectors).

inform and be informed; angry when strategy is not respected or honored

wait receptively and responsively for an internal affirmation of response; frustrated when not asked for response or when response is not accurately perceived

multi faceted strategy of waiting receptively and responsively for internal affirmation of response, then imaging the response as manifesting and revising where appropriate, then informing and being informed. When not honored in strategy, frustration and anger surface.

recognition of their energetic perception; an invitation for a projector is a hook up of their energy for expression. This Strategy when followed results in feeling validated, and, when not followed, results in feeling left out or bitter.

open vehicle allows for vulnerability to others and to energies that are conditioning fields. Strategy allows movement and expression along with the movement of the transits and of others. Sense of being in the flow when the strategy is followed and of being disappointed, let down, or powerless when not followed.

An individual who has No Definition in Type is someone in whom the Design Chart has no channels defined; these individuals are Reflectors.

A Single Definition Type applies to a chart where there is definition in a channel or more than one channel and the channel or channels that have definition form one stream of connected energies. A Single definition person is at some level self-contained because their definition forms a single potential of energy, which reliably flows in them.

A Split Definition occurs when two areas of separate definition do not connect to each other. Because of this split in the flow of energy in the split definition chart, that person always seeks a bridge to link the separate energetic definitions together.

The Triple Split Definition person is someone who has three separate channels of definition in their Design Chart that do not connect to each other in the defined channels of energy flow. These individuals need several bridges to connect these defined channels.

The Quadruple Split Definition is someone who has four separate channels of definition in their Design Chart that do not connect to each other in the defined channels of energy flow. Often these individuals have all centers defined but not all connect to each other.

(For statistics analysis of the frequency of occurrence of different Definition Types see, "Statistical Analysis of Definition Type in the Human Design System, Waking Design Chart," by Eleanor Haspel-Portner, Ph.D., on the www.unifiedlifesciences.com web site in the Research section).

a Defined Solar Plexus always results in Emotional Solar Plexus Authority in the chart. Depending upon the channel defined to the Solar Plexus the energy of the person's emotional wave varies. The important strategy for someone with Emotional Solar Plexus authority is patience in waiting out the emotional wave pattern (the pattern of the wave occurs over time).

a defined Sacral Center but an undefined Solar Plexus Center and no motor connection to the Throat Center gives Generated Authority. The Sacral voice in this instance has only a response which reflects an energy toward or away from involvement in activity or process.

definition in the Splenic Center allows spontaneous operation through the awareness of intuition, instinct, or taste; such authority coming from the splenic center has a very quiet voice which speaks internally only once in the now. Splenic awareness may be Manifesting, Generating, or Projected depending on the path of definitions in the chart.

none of the other definitions can be present in this kind of authority; the person with the Ego defined to the Throat Center uses "personal" will to decide what they want to manifest.

only the Self Center to the Throat Center is defined in this type of authority. It allows an individual to look inward to the Self for clarity in decision-making. The mind, even if defined, never has inner authority, but the mind can have outer authority, i.e., be of use to others.
