Phi is a FUNCTION—the primordial algorithm.
The ratio of a : a+b can be written as 1 : 1.618. Phi (Φ) recurs infinitely and is also known as dynamic, because in a sense it’s alive. Unlike the Fibonacci spiral, you will NEVER see a golden mean spiral, nor can you graph it. Like a vibration or energy field it may be felt or experienced, but because it is an infinite spiral it is not bound by finite mathematics.
It may help to think of Φ as the divine drummer, pulsing out the base beat of the universe like a sacred heart.
