Answer: In spirituality, the logic of our world is not preserved. There is no arithmetic there, but there are many other different calculations depending on what one is working with. We will have different mathematics on different levels.
Question: Is spiritual arithmetic the Gematria of words? Is it related to the desire?
Answer: Of course, because each letter in itself represents the combination of various proportions of the forces of bestowal and reception, each of which creates one particular basic form or another. That is why the 22 letters of the Hebrew alphabet are the basis.
The first nine letters correspond to the nine Sefirot of Bina, the second nine letters are the nine Sefirot of Zeir Anpin, and the four final letters are the four Sefirot of Malchut. There are also five additional letters, which are formed from the Parsa.
Question: Each element of the letters: the point, the horizontal line, the vertical line—are all these forces?
Answer: Yes. A specific combination of forces of bestowal and reception represents letters. There is no other combination.
The Creator created the desire to receive (the black point). During the desire’s development process, He was constantly exerting influence on it and gathering all possible combinations of His influence. That is why when the black point is reflected on the background of white Light, it depicts the correlation between the upper Light and itself, its desires. This creates the 22 patterns.
The laws of Gematria are the same everywhere, the ten Sefirot do not change. But this is not reflected in the mathematics of our world. Gematria is one of the languages describing the upper world and its processes. This is the language of Kabbalah.
