 See, the dimensional levels are separated by 90 degrees. Musical notes are separated by 90 degrees. The chakras are also 90 degrees. It's a number that continually appears. Probably at this point, we should get a common understanding of what dimensions are, like third dimension, fourth dimension, fifth dimension. What are we talking about here? Most people think of dimension in terms of time and space, the x, y, and z axis, with time becoming the fourth dimension. This is not what we are talking about. What we're seeing as the various dimensional levels has more to do with music and harmonics than anything else. A piano has eight white keys from C to C, which is the familiar octave, and in between there are five black keys. Together, this creates what is called the chromatic scale, which is 13 notes, well, actually 12, with the 13th being the first in the next octave. So from one C to the next is really 13 steps, not eight. This also correlates with the seven, eight, and 13 chakras system I mentioned in lesson two.
