Part 13 · Chapter 141

And this is the meaning of the words Tzitz and Tzitzit: Tzitz is the gazing of Arich Anpin upon Zeir Anpin, and Tzitzit is the gazing of Zeir Anpin upon his Nukva. Now, through the striking of that lock of hair upon the Mochin of Zeir Anpin, their illumination goes out and protrudes upon his forehead, and it is called the male Tzitz. And the illumination of the Mochin of the head of the Nukva, which protrudes through the striking of that lock of hair, is called the female Tzitzit.
