The I Ching is based on a set of binary mathematical permutations, which also underlie what I call the "pure" progression of the Mayan number harmonics - 2, 4, 8, 16, 32, 64. As it is presented to us, however, the I Ching is actually comprised of the combination of eight symbols (trigrams) of three lines, either broken or unbroken, in all possible combinations with each other. By doubling the trigrams, the permutations yield 64 more complex symbolic possibilities of six lines each (hexagrams). By comparison, the zolk'in is based on permutations of thirteen numbers and twenty symbols or Sacred Signs which yield a possibility of 260 permutations. At minimum, each one of the 260 permutations is a combination of one of thirteen numbers, one of twenty signs, and one of four directional positions.
Finally, like the I Ching, the Tzolkin is a system for revealing information relating to a deeper or larger purpose. While the I Ching is precisely synchronized with the genetic code, the Tzolkin is synchronized with the galactic code. As the genetic code governs information concerning the operation of all levels of the life cycle, inclusive of all plant and animal forms, the galactic code governs information affecting the operations of the light cycle. The light cycle defines resonant frequency ranges of radiant energy, inclusive of electricity, heat, light and radio waves that inform the self-generative functions of all phenomena, organic or inorganic. The two codes are obviously interpenetrating and complementary.
