The Natural A432 Scale is recognized as a fundamental frequency found all around in nature.

432 a principle of natural harmonics

It is a principal of natural harmonics that resonates the properties of light and consciousness. It seems that the universe is based on harmonic series such as 72, 144, 432.

A440 is an arbitrary standard. I try to avoid it as such. The difference between 440 Hz and 432 Hz is as “little” as 8 vibrations per second, but it is a true perceptible difference.

Most music worldwide has been tuned to 440 hertz since the international tuning standard was changed.

The change in tuning standard supposedly happened in the late 1930, early 1940 following the recommendations of the Nazi party spokesman, Joseph Goebbels.
This might actually be anti-nazi propaganda as there don’t seem to be any real documentation supporting this notion (that I have seen so far).
It is however stated that it was the Rothschild-Rockefeller (Illuminati) alliance promoted the change in standard and who influenced the British Standards Institute (BSI) to adopt the A440 tuning in 1939.
The reason for changing the tuning from the natural scale, of A432 or C256 to the A440, and who actually forced the “new” standard will not be discussed here.
Whatever the reason, I think one should just strive to use the natural A432 scale for yours and others well being.
Bruce Cathie describes 144 as a perfect harmonic of the speed of light, which is 144,000 nautical miles (144,000 minutes of arc per Earth grid second) in the vacuum of space.
Each of these harmonics are literally a mirror, or a cascade of mirrors within mirrors, that 8 hz can look into. For example 144 is 18 x 8 hz, and 72 is 9 x 8 hz. The way that light travels in space is thus a 144 decimal harmonic (144:144,000).
…the fundamental harmonic of light in geometric terms has an angular velocity of 144,000 minutes of arc per grid second. The reciprocal harmonic of light or 1/144,000  repeating .69444. This harmonic refers to the negative reciprocal light, which in theory forms the basic building block of the  anti-universe of light or negative reality.
Jamie Buturff has done extensive research into the 432Hz frequencies and I recommend his work. He has also some major insights into chakra frequencies as well that is partly based on information from Tibetan monks who plays on handmade chakra bowls.
