Its khaballistic (I think that's how you spell it?) The Hebrew language. The letters have number meanings so the word for spirit (ruach) has the same numerical "meaning" as ab the father and Ben the son (the original Hebrew words) so you see where the trinity comes from, ab, Ben, ruach all having the same numerical meaning, so kaballisticaly they are interchangeable. But if you take a phrase from then old testament, and put it into a kabal square (3*3 or 4*4 or etc) letters across and down, in its original ancient Hebrew lettering, the passage can be read going across, going up and down, and in a diagonal, like:
1 2 3
4 5 6
7 8 9
would be the same words if you start with the 1 and go
123, 456, 789
Or start with the 9 and go
963, 852, 741
But... If there is a capital letter it changes the value by a factor of 10.
So ab the father is 3 (a=1 b =2)
But Ab the father would be 12 (A=10, b=2)
But.. AB the father would be 30 (A=10, B=20)
So then if you look at it even further... Entire sentences are hidden in singular words.
Aliester Crowley wrote a book about it. I had a book that explained some rituals of king Solomon and of ancient Hebrew wording (the very first sentence in the old testament in original Hebrew can be read forwards, backwards, upsidedown, top to bottom, diagonal to diagonal, and encoded within the wording is the words ab, Ben, ruach. Life/breath, etc.
