Your tri-center consists of your dominant type in each of the three centers of intelligence with a preferred ordering of the centers (types). The preferred ordering of the 6-4-8 is:

1. Primary Center: Head (Type 6)
2. Secondary Center: Heart (Type 4)
3. Tertiary Center: Gut (Type 8)

Type 6 is located in the 567 triad which is often described as the head or head-based center.

Although the head types can be thought of in terms of reasoning, analyzing, and other typical thinking functions, a useful distinction from the other two centers can be made in terms of anticipating and preparing for future possibilities.

This may involve gathering data and facts in order to better predict outcomes, preparing for negative potentialities that might occur, and planning or pursuing activities that provide enjoyment and avoid discomfort.

Type 6 thinking often leads to doubts and questioning. This can take place regard one's own thoughts as well as those of others. Some sort of assurance or guidance may be sought in resolving doubts and making decisions. This could come from people, authorities, or systems of thought that over time have shown consistency and been found to be trustworthy and reliable. There can also be a reactionary impulse to jump into action in order to purge any doubts or fears.

Type 6 Fear

The fear triad consists of types 5, 6, and 7. Fear for these types involves the head center. It can be thought of as a negative anticipation of future possibilities and wanting to prepare for or avoid those possibilities.

This may involve learning as much as possible in order to feel competent and knowledgeable, imagining worst-case scenarios and preparing for them, and having alternatives available to avoid being trapped in discomfort or pain.

Type 6 fear can come from imagining worst-case scenarios. This can not only create a cautiousness and seeking of security but also a prepared readiness for the possibility of these scenarios. A general anxiety and sense of doubt about the future and one's own capabilities may be present as well.

Type 4 is located in the 234 triad which is often described as the heart or heart-based center.

The heart types are focused on interpreting, expressing, and reacting to one’s own emotions or the emotions of others. More specifically, the heart center focuses on what's emotionally significant in the sense that emotions are an indication of how strongly a person resonates with or against something or someone.

This may involve being attentive to the emotional needs and desires of others, seeking emotional affirmation for oneself from others, and expressing one's own unique emotional impression of the world.

Type 4 has emotional impressions of the world which create a rich internal emotional reality. They base their sense of self on this. To express or share this inner emotional world is to share oneself. It can be challenging however to find a way to do this. It can seem like others don't have this same emotional senistivity which can also make the type 4 feel different from other people. This sense of difference can alternate between feeling defective and feeling special.

Type 4 Shame

The shame triad consists of types 2, 3, and 4. Shame for these types involves the heart center. It can be thought of as a feeling of deficiency for not living up to a more idealized sense of self.

This may involve initiating connection with others to avoid feeling unlovable or unimportant in the lives of others, finding value and worth through performance and accomplishment, and finding significance by cultivating and expressing one's uniqueness.

Type 4 shame comes from feeling different from others. It can seem like others are more capable in areas that the type 4 is not. This can sometimes lead to a sense of defectiveness. In compensation, they may search for what makes them uniquely special and try to live from that sense of self instead.

Type 8 is located in the 891 triad which is often described as the gut or body-based center.

There are several ways to interpret what the gut or body types represent. They may be thought of in terms of sensory-somatic (bodily felt sensation), sensory-motor (physical movement and activity), or instinctual (gut decision making).

This may involve taking action based on one's gut instinct, getting pulled along by the agenda of others, and actively trying to correct what's seen as wrong in the world.

Type 8 can be very direct in going after what they want. There's a big energy available that they often have to sit on so that others aren't overwhelmed by it. The desire is to freely express it and be true to it. They often jump into action by making decisions from the gut instead of taking time to carefully think it through. While this gets things moving and makes things happen it can sometimes cause problems or damage that may have to be repaired later.

Type 8 Anger

The anger triad consists of types 8, 9, and 1. Anger for these types involves the gut or body center. It can be thought of as an energy of will that pushes against obstacles to create movement or resists being pushed.

This may involve pushing through obstacles to get what one wants, stubbornly resisting attempts to be pushed in an undesired direction, and getting people to see what's right and correcting things not done right.

Anger for type 8 is an energy readily drawn upon when needed. It's used to push through obstacles and make things happen. Confrontation often comes easy. It clears the air and gets at the truth of things. When the type 8 or others are unfairly taken advantage of it can sometimes come back as a vengeance to get even or rebalance the scales of justice.
