“There are four letters in my name,” He said, “traditionally. For this I am called, Tetragrammaton, which is Greek in derivation, though I am not, neither Semitic, nor of any other people of Nations. It is better to say they are of Me.”

Later I was three, and I was one; and what contains One contains Everything.”
