The little chart behind it all

Letters become numbers.

Find a letter in the right column. Its number is on the left. That’s all there is to it.

Let’s try DONALD.

D = 4, O = 7, N = 5, A = 1, L = 3, D = 4.
4 + 7 + 5 + 1 + 3 + 4 = 24 → 2 + 4 = 6.

24 is the compound number. 6 is the root number. If a total is above 52, we add its digits until it reaches 52 or below, then reduce it to one digit for the root.

What about 9?

9 is treated as sacred in the Chaldean tradition and is not assigned to any letter. It can still appear when we add up or reduce a name.

Spaces, numbers, and symbols are ignored. For the inner-self total, the vowels are A, E, I, O, U. Y is counted as a consonant.
