Chochmah, Binah and Da’at of Zeir Anpin Three lights shine within the cranial cavity – Chochmah, Binah and Da’at. You may argue, you speak of three, yet there are four as I said that they are the bequest of his father and mother (Chochmah and Binah, which pertain to the aspect of Aba and Ima that he inherited), and the two parts of Da’at hidden in them. They all become crowns on the head of Zeir Anpin; they are the head Tefillin.
He answers, they are four lights at first, merging afterwards at his sides. The two parts of Da’at merge into one to reconcile Chochmah and Binah and unite them with each other. They thus turn into three lights and shine and penetrate the three cavities in the skull, each to emerge from its own side, one to the right, one to the left and one in the center, and they spread throughout the body.
