These structures might be defined somewhat differently to most energy-bodies, but are a vital part of a composite human.
There are five locations (for humans with an Ultimate-self), each of which has an instance of the same personality-definition structure inside it: one is about 1.5m below the feet, one is about 25cm in front of the belly, one is about 20cm above the head. Note that the definition-structure in front of the face is a separate structure, not part of the same system.
For humans with an Ultimate-self, another location is near the end of the Between-lives sequence (in the relevant Pocket-universe), and another (the most senior) is above one’s location just outside the Playing-field of the Physical-universe. The last section of the Between-lives sequence forces a being to choose one of the personalities (based on configurations of limitations and aims), and then one chooses a baby body to take ownership of, which (usually) fits that personality (different personality types have different typical body shapes).
The personality-definition structure defines which ifa personality type (“archetype”) the person has . . . these are strong influences on various aspects of the personality (including sexual orientation). The three personality-definition locations near the body have the definitions expressed in both Magick-universe, and Physical-universe building-blocks (there are often more than one Magick-universe definition which fits each of the Physical-universe personalities, resulting in sub-types). The two other locations have only the Magick-universe version of the definition.
Occasionally there are problems with the definition structures, such as the one implemented near the end of the Between-lives sequence being unclean (such as if an alternative option was also wanted) or not being a match for the one used by the body one owns. This can cause problems in a person’s life.
Each of the pre-set personalities confers specific areas which are likely to be relatively easy and successful for that personality, and also many strong limitations. Humans in very good spiritual condition don’t use any of the personalities, instead they have the all-options structure, which means all of the possible items at full power, which confers all of the benefits and none of the limitations. This all-options configuration would also handle any problems with the definition-structures, such as things I mentioned in the paragraph above. (I’d recommend also handling the original causes of the problems with the personality definitions).
