What Is the Holy Tetraktys in Numerology?

Ten points from one birthday

The classical tetraktys is 1 + 2 + 3 + 4 = 10 — the Pythagorean diagram of how the many come from the one. This house uses the inverted-triangle method laid out in Oliver Tan’s Power of Numbers (citing Hal A. Lingerman): date, month, and year reduced in pairs until the triangle is full. A 00 pair is read as 5.

Interpretive language on the page is original Diamond Bright writing in that system — not a reprint of Tan.

What it is not

It is not the Divine Triangle. Javane & Bunker walk nine-year squares with the name. The Tetraktys is only the birthday. Transits & Essence are a third clock, and they use the Chaldean name chart. Three maps. Do not stack them into one number.

Wu Xing, labeled when we use it

On this page the house also pairs digits with the He Tu / Wu Xing elements — metal, water, fire, wood, earth — and says so. That pairing is a cousin system, not Pythagorean doctrine. The Life Path itself stays the three-part Western reduction. See Life Path and planets for the rest of the correspondence shelf.
