Part 12 · Chapter 278

And the reason of the matter is that the Gevura is the crown (Itra) of the Nukva of ZA, and it was given to her. And behold, the Nukva is called Dalet, as is known, and it is the secret of the Dalet in this Aleph, whose form is Yud, Vav, Dalet. Therefore it is in its lower point, but the upper point, which is the Yud, is in the GAR, and the Vav between them is of ZA. Therefore, to hint that it is the crown of Gevura, which is for the sake of the female, it was formed in the form of Yud, Vav, Dalet.
