There is no representation of the human being that fully conveys all its complexity, so it should not surprise us if religions and various philosophical systems do not all have the same perception of its structure. All are correct, it depends on the perspective from which we view it. When we want to give an idea of the anatomy of the human being, for ease of understanding, we are obliged to make different charts representing the different systems: skeletal, muscular, circulatory, nervous. The same applies to the psychic organism: just as an anatomist, a Mystic uses different diagrams or divisions depending on the aspects of the human being and the subjects he wishes to explore.
