Numerology is the esoteric study of numbers. Many occultists love to debate the origins of numerology (of course, many occultists love to debate everything) and it is generally accepted that the form used in Western society today is derived from the teachings of ancient Greek mathematician and mystic, Pythagoras. Others place the origin of numerology with the Babylonians, Phoenicians, Egyptians. Hebrews. Hindus, and Chinese. To be honest, it doesn’t really matter to me. It works, and that is what gives me a happy.
The form that I use is generally called “Chaldean Numerology” and is attributed to the ancient Chaldeans and Babylonians. The big difference between various systems is that the letter values are different. The number meanings stay relatively the same, regardless of whose system you are using.
I use the Chaldean system over the Pythagorean system because it assigns numerical value to letters based on their sound, not on the order in which they occur in the alphabet. The Pythagorean system assigns letter values based on order: A=1, B=2, C=3, etc, and to me this always felt contrived. I used to be apologetic and say that one is not better than the other; it really is just a matter of personal preference. Honestly, I don’t believe this. The Latin alphabet that we use today wasn’t the same in Pythagoras’ day, so there is no way on earth that he could have dreamed up a number/letter system that corresponds to modern English.
The numerological order of numbers to letters feels just plain wrong. Some numerologists insist that the Pythagorean is better than the Chaldean because it is more “modern”. Considering that Pythagoras was born around 580BCE, I am inclined to squint in their general direction.
