The sun is the energetic center of our solar system. It is the center of gravity, the earth and other planets circle around. Therefore the frequency of the sun is associated to the pyhsical center. In ZEN this point is called Hara. It is the center of gravity for the human being as well as the sun is the center of gravity for our solar system.
The frequency of the sun is the expression of a limit because it is the only tone, where an astronomical period is not raised to a higher octave. Like the absolute temperatur zero point means the limit of expansion and contraction, the limit that is also called gravitational lenght.
An imaginary planet that would circle around the center of the sun within the distance of the gravitation lenght and with approximate light speed would do that about 32000 times in a second. The 8th under octave then has a frequency of 126.22 Hz. The corresponding colour is green to yellow -green with a wavelength of 540 Nanometer.
The frequency of the sun is the tone of the 20th century. It does not represent classical pyhsics as all the other indroduced tones in this booklet do, but the modern quantum theory and the relativity theory. The tone of the sun is the border between Yin and Yang, between this side and the other side. It rises out of a higher dimension and depriving itself of rational observation it stands for the magical and the transcendental.
The sun tone should be used, after having worked with the other tones and is most of all for advanced parapsychological navigators. The experiences, that are possible with this tone, therefore have a multidimensional character and one is catapulted into absolutely new fields of existence.
"Meditation carried out to this tone will lead to state beyond good and bad, shame und guilt, beyond space and time, knowledge and wisdom, action and rest an being and not-being. It leads to a state where being has no name, to a state where the all-one and the all encompassing are no longer separate entities but are reunited at their one common origin, the origin that is also you."
