- Three triads are evident in the Tree of Life. The top triad is Yechidah (spirit), the middle triad is Chiah (soul), and the bottom triad is Neshamah (mental body), Rauch (emotional body) and Nefesh (etheric body). These terms will be described in subsequent chapters.
- Each of the seven planes has seven subplanes, which are numbered in the central column of the diagram. The pattern of the seven planes repeats itself on a smaller scale (like a fractal does) in the subplanes. This will be expanded upon later in the chapter.
- The planes are "created" from the top down, but I have numbered the planes from the bottom up, which goes against convention, but it is far easier to relate to when the low ones have low numbers and the high ones have high numbers. This will become evident later in the book when we discuss the multi-dimensional aspects of man and the evolution of consciousness.
- On the right-hand column the planes appear to overlap each other. This represents the energies of the planes influencing those "next" to them. This results in the upper and lower halves of some planes having slightly different properties to each other. For example: the top half of the physical plane is called the etheric plane, and the top half of the mental plane is called the causal plane. The monadic and spiritual planes are similarly divided but these haven't been given separate names. The various planes and subplanes will be fully described in Chapter 10.
