Fig. #2. The diagram above shows the box within a box, within a box repeating pattern of the nature of creation. The ancient Magi believed that there were five parts to each Human-form--1. The Ka, residing upon Lower, Middle Earth; 2. The Ba, residing upon Middle, Middle Earth; 3. The BaKa, residing upon Lower, Higher Earth; 4. The Sacred Ka, residing upon Middle, Higher Earth; and 5. The Soul, residing upon Higher, Higher Earth, but it reflected a part of itself upon all levels of experience.
The first importance was the level upon which the individual lived and breathed. They [the magi] called it The Ka, because it was physical in nature, it was limited to The Astral Plane of Common Reality. It was said to walk the Un-holy Path, because it depended upon the physical for its sustenance.
The second important level to each individual was that part of each which survived after the death process. They [the magi of old] called it The Ba, because it was said to walk the Holy Path--it did not depend upon the physical for its sustenance. The third level of importance was considered to be the life-form's essence. It was called The BaKa, because it remained un-effected by the laws of creation, as they knew the laws to be.
The fourth level of importance to each individual was seed for the life-form's God-like nature. They called it The Sacred Ka--it was said to have the ability to commune directly with Orthodontiks, The Universal Nest, so to speak.
The fifth level of importance, yet the most important to the world of the physical, was a life-form's Soul. Its importance came from the fact that is was a complete recording of everything the life-form did during its Earth Experience. It was, indeed, seed for the power of Karma.
