Definition describes how your defined centers are connected. When they form one continuous block, energy flows without interruption. When they form separate groups, there are gaps that other people or transits tend to bridge. It changes how you process information and who makes you feel complete.

The types of definition
- ✦Single definition: all defined centers are connected. You process on your own and tend to feel self-sufficient.
- ✦Split definition: two separate areas. You may look for people who bridge the gap. A small split needs one gate; a large split needs a whole channel.
- ✦Triple split: three separate areas. You process through different people and environments and benefit from not rushing.
- ✦Quadruple split: four areas, very rare. You need time and variety of contact to reach clarity.
- ✦No definition: all centers open. This is the Reflector.
Why it matters
People with split definition often feel that 'something is missing' and look for it in relationships. Knowing that it's a mechanical feature —not a personal flaw— helps them choose relationships from authority instead of need.
Frequently asked questions

Your defined centers form two groups that aren't connected. People who bridge that gap can feel very attractive or 'completing'.
Which definition is the most common?+
Single and split definition are the most frequent; triple and quadruple split are much rarer.
