Few figures in history have left as profound an imprint on Western thought as Pythagoras. More than just a mathematician, he was a philosopher, mystic, and spiritual teacher whose ideas transcended disciplines.
His discoveries in mathematics, music, and cosmology laid the groundwork for scientific inquiry, while his mystical teachings influenced esoteric traditions for over a millennia.
Yet, much of his life remains shrouded in mystery. Who was Pythagoras, really? And how did his fusion of logic and spirituality shape the modern world?
This is the forgotten story of one of history’s greatest polymaths - a man who didn’t just revolutionize Western civilization but changed the very way we perceive reality.
Before Pythagoras became a legendary teacher, he underwent a radical transformation. His journey into wisdom began in Egypt, where he sought initiation into the ancient mystery schools. But gaining access to their secrets was no simple task.
The priests required him to undergo a fast of 40 days - a period of purification meant to cleanse both body and Mind. Only after this intense spiritual preparation was he permitted to enter their sacred halls.
Within these temples, Pythagoras absorbed knowledge that would define his later teachings:
Geometry & Mathematics – The Egyptians had long understood geometry as a divine science, used in temple construction and astronomical calculations.
Metempsychosis (Transmigration of Souls) – The belief that souls reincarnate across lifetimes, a concept Pythagoras would later teach in his own school.
Cosmology & Astrology – The alignment of earthly knowledge with celestial patterns.
This initiation was more than just education - it was a rebirth through a baptism of knowledge. When Pythagoras emerged, he carried with him the seeds of a philosophy that would reshape the ancient world.
Pythagoras’s most famous declaration—"All things are number"—was not merely a mathematical statement but a metaphysical one as well. To him, numbers were not just tools for calculation- they were the hidden language or cipher of the universe.
The Sacred Tetractys: The Key to Cosmic Harmony
Central to Pythagorean thought was the tetractys, a triangular figure composed of ten points arranged in four rows:
This symbol was sacred because:
It represented the perfect number (10), the sum of 1+2+3+4.
It encoded the four elements (earth, air, fire, water).
It symbolized the structure of reality, from arithmetic to music to the cosmos.
For Pythagoreans, meditating on the tetractys was a path to divine understanding.
One of Pythagoras’s most revolutionary contributions was his discovery of the mathematical foundations of music. Using a monochord—a single-stringed instrument—he demonstrated that musical harmony was governed by precise numerical ratios.
By dividing the string at specific points, Pythagoras uncovered the intervals that form the basis of Western music:
1:2 ratio → Produced an octave
2:3 ratio → Produced a perfect fifth
3:4 ratio → Produced a perfect fourth
This revelation was monumental. It proved that beauty and order were ONE and could be expressed mathematically—a concept that would go on to influence everything from Renaissance art to modern physics.
Pythagoras took this idea further, proposing that the planets themselves which moved in the same harmonic ratios, created a cosmic symphony—the "Music of the Spheres." Though inaudible to human ears, he believed this cosmic harmony could be perceived by the Soul.
The monochord, then, was not just an instrument but a philosophical bridge—linking the physical world to the unseen order of the universe.
Upon returning to Greece, Pythagoras became a spiritual teacher whose doctrines blended science and mysticism.
Pythagoras taught that Souls are eternal, cycling through multiple lifetimes. He claimed to remember his past incarnations, including one as Euphorbus, a Trojan warrior. This belief in reincarnation would later influence Plato.
In Pythagorean teachings it was taught that the Soul was linked to the number 5 and to the geometry of the pentagram.
The pentagram, with its golden ratio proportions, was a revered Pythagorean symbol. It represented:
Health and vitality (the five elements)
Mathematical perfection (the golden mean)
Hidden cosmic order
Ancient accounts describe Pythagoras as possessing supernatural abilities:
Predicting earthquakes and political events
Communicating with animals ( in one account, he famously convinced a bear to stop attacking a village)
Bilocation (appearing in two places at once)
Whether myth or reality, these stories highlight how Pythagoras was seen as a figure between worlds—part scientist, part mystic. Most of the more likely exaggerated tales came about by pupils in his school.
Pythagoras’s school in Croton, Italy, was more than an academy - it was an extremely secretive religious order with strict rules:
Communal living (all property was shared)
Dietary restrictions (including a ban on eating beans, for obscure reasons)
Vows of silence (new initiates were forbidden from speaking for five years)
The Brotherhood’s teachings were divided into exoteric (public) and esoteric (secret) knowledge. Those who revealed the inner mysteries allegedly faced expulsion—or worse…
Though the original Pythagorean school was eventually destroyed, its ideas lived on:
Plato incorporated Pythagorean mathematics into his philosophy.
Kepler used the "Music of the Spheres" concept in his astronomical models.
Modern physics echoes Pythagoras’s belief that reality is mathematically structured.
Even today, we see his influence in:
Sound healing therapies (using frequencies for wellness)
Sacred geometry in architecture
The search for a "Theory of Everything" in physics
Pythagoras was more than the man behind the famous theorem we all know. He was a visionary who saw numbers as divine, music as cosmic, and the Soul as eternal. His legacy is the marriage of reason and wonder - a reminder that the universe is both calculable and mystical.
In an age where science and spirituality often seem at odds, Pythagoras’s teachings offer a timeless lesson: Truth is found not in division, but in Unity.

I much prefer the Aristotelian view wherein numbers are accidental properties of matter. And numbers beg the question of identity as in 3 what? Kinds. Intellectual abstraction literally. And numerology is still popular in some cults. Plato seemed to have a significantly more integrated spiritual view.
Pythagoras and the Tetractys specifically have greatly influenced my work, he was such a brilliant mind. I recommend the “Pythagorean source book and library” highly
