The next question is what are the other Mayan underworld frequencies that possibly map to the human brain wave region? Using the radius of the Earth, Re = 6,371 km we can calculate what the value for f9 is. Let the delta radius decrease from the surface of the Earth by the radius value Re divided by 21 (versus 9), to get a step size of 303.381 km towards f9 and the center of the Earth. Other step sizes will be used to span the frequency limits shown in the tables above that range from Delta to Beta brain wave regions.
The frequency table derived using 3*7 versus 9 produces the table below. Until the target frequency is known, the divisor is a guess. Dividing by 9 dimensions did not produce the brain waves in the region expected. Note that two different sources for the human brain wave regions (references below) differ significantly so the overlapping range from the two tables was used in the summary brain wave table shown in the sketch.
The key point here is that if one could figure out what frequencies map to the Mayan 9 frequencies, then most likely 7 of those 9 frequencies correlate to the human Chakra frequencies in the human energy body detailed in my books as EQ5A, the maximum human energy equation. Since we know the colors (wavelength = speed of light divided by the frequency) of the Chakras, we will compare them with those toyed with in the tables below and possible find the right divisor for the Re parameter that will properly map the Mayan Frequencies to the proper brain wave region. Once this is definitively known, then a simple multi-tone generator can be used to create binaural audio beats that entrain the brain to the desired frequency. In essence, by so doing, one has the possibility to visit each of the 9 parallel dimensions discussed in the Emerald Tablets. This sketch is the next one that will be made digital for ease of interpretation.
