Part 13 · Chapter 189

However, there is this difference in Arich Anpin more than in the other Partzufim: for in his skull there are Keter and Hochma, but Bina and Daat are not in his skull. And the Bina of Arich Anpin is the secret of the throat of Arich Anpin, and there it descended, and it does not stand in the head. And from here you will understand how Bina is called "throat," and is called "Keter," and is called "shofar," for the throat of Arich Anpin becomes the Keter of Aba veIma.
