Fibonacci Forks 89 Hz and 144 Hz

Updated: Jul 12, 2023

The Fibonacci sequence is a series of numbers where the next number is found by adding up the two numbers before it.

The sequence goes: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, and so on.

These two weighted forks are the 11th (89 Hz) and 12th (144 Hz) positions in the Fibonacci sequence.

When you divide any number in the sequence by the number ahead of it, you get roughly 1.618, which is Phi, or the Golden Mean.

The Fibonacci sequence

Our bodies are electrical waves informed by geometry. With the other pair of Biofield Tuning weighted forks (62.64 Hz and 54.81 Hz), we induce (through binaural beats) the Schumann Resonance, the natural background pulse of the earth's electrical signal, into the body's electrical system.

With these forks we induce the geometric information of the natural harmonics of the unfolding of nature, in perfect proportion. The effect on the body is one of being able to rest more in the ordered geometry that underlies the composition of the human body. One user described them as creating a sense of a “bright inner order”.

The Golden Mean in Nature

For those of you who have read Tuning the Human Biofield, you may recall that geometry is an inherent property of the aether. So one way to look at these forks is that they help bring order to your geometric template, your etheric body, while the other pair helps bring order to your electric, or plasma body.


My original intention had been to create a companion fork for the Sonic Slider, a new pair that would be a smaller, easier to use set that was based on the Schumann Resonance. However, when I used the prototypes of the forks that were 7.83 Hz above and below the Sonic Slider (93.96), I found neither of them useful or pleasing. In fact, sliding with both of them was pretty much awful, and it gave me a whole new appreciation for the fairly universal appeal of the vibration of the Slider.

So, instead of releasing the “Sister Slider” as some people were anticipating, I am sharing these forks instead. I originally had them made a year or so ago and have been using them here and there, but for the last few months I have been using them regularly and really loving them.

Like the Sonic Slider, they have extra long handles, and unlike the failed sister forks, they are both pleasant to slide along the body as well. I have been using them both with boots as well. So far, everyone who has used a pair has said the same thing - I LOVE these forks!

The Fibonacci pair is not required for Biofield Tuning students and are not part of our toolkits. However students who like to experiment and discover will definitely enjoy adding these to their practice. They can be used wherever and however you use the weighted forks you are already using.

Cool photos, it’s clear that the master has experience and understands photo composition! Until recently, I myself didn’t understand much about this until I read article It says how to practice photographic composition and what composition is in photography!

Ukraine is currently at war and thousands of innocent people are dying, who simply lived in their own country and did their usual things. Russia has declared war on Ukraine and is killing civilians. To read true information or help Ukraine go to the site.

This fund provides assistance to the Ukrainian military and brings Ukraine's victory over Russia closer.

Russia stepped in to stop the slaughter of innocent people in Ukraine by then current nazi regime. Do take the time to discover the facts.
