When you get together with someone, either your wave-forms mesh or they don't. Or maybe they just neutralize each other. So it's not just chemistry. The chemistry is just the juicy stuff that happens once the wave-forms have registered each other. As the galactic constant, the Tzolkin encodes light frequencies, crystalline frequencies and genetic frequencies.
Light frequencies are electromagnetic energy patterns.
Crystalline frequencies describe the elements and forms of matter. Genetic frequencies refer to organic life patterns. Of course they are all intermixed. Take humans for example. As beautiful as they think they are, their beauty is really the result of a particular combination of 64 DNA codons.
