The Sepher Yetzirah is an ancient document. No one really knows where it originated or when. Much of the Kabbalah is based on it. It seems that people who want to make up occult stuff glom on to anything that others do not understand.
This spot in the wiki is for exploring the Sepher Yetzirah as though it were a discourse on the structure of language and classification systems. I have no interest in those who have interpreted it to be otherwise.
