Part 9 · Chapter 77

Hotam [seal] is also from the language of a thing that is stamped in another place, its shape remaining in it. That is: the Yesod is called a Hotam because, as has already been explained above, the measure of the length of the Yesod of ZA [Zeir Anpin], set opposite the middle line of the Nukva [female] who stands facing him at his back, is until the end of the Tifferet in her. Accordingly, all the rest of the Sefirot in the female are aligned opposite the NHY [Netzah-Hod-Yesod] of ZA, and they have something upon which to lean.
