Part 13 · Chapter 146

And moreover, I have heard another discourse from my teacher, may his memory be for a blessing, on this matter: that the barbs (Kutzin) are drawn and issue from the brain of Hochma of Zeir Anpin; the locks (Nimin) from the brain of Bina of Zeir Anpin; and the hairs (Se'arot) from the Daat of Zeir Anpin, which includes Hassadim and Gevurot. And "lock" (nima) in gematria is one hundred, which is the secret of the Name of Sag (63), and its filling, which is in gematria thirty-seven when you remove the simple letters; and Sag (63) and thirty-seven are one hundred. And it is known that this Name is in Bina.
