Part 13 · Chapter 92

*After the subject of the three heads of Arich Anpin was explained in the previous chapters — namely the skull (Galgalta), the air-space (Avira), and the brain (Mocha) — and how each aspect of them contains three aspects, which are three Names of YHVH, as above. Now, each Name of YHVH of them has four letters; hence twelve letters are found in each head, and the inclusive [one] is thirteen, which is the head itself, which contains within it one Name that includes the three Names that emerged from it. Therefore, certainly, these thirteen aspects that are found in each of the three aforementioned heads — the existence of their illumination must be revealed externally.
