The mind understands logic. The brains' structure is a mirror image of the minds' structure but the minds structure is simpler. The minds' structure is similar to the stars in a galaxy. A galaxy s stars are more random than the mind s thoughts and memories are. The soul is the beings unique portion of spirit.
Soul also has the power to remember.
The souls' structure is even simpler than the minds' structure of memories. It is not a structure at all. It is the least complex of the spaces but is equal in area. Chi energy is of the soul space. Chi follows consciousness, healing follows chi.
