אדני Lord or master.
The name of Malkuth in Atziluth is Adonai; thus, when we are working with chastity in Malkuth, we are assisted by Adonai. This why the prophet Habakkuk 3:19, said:
“Jehovah the Lord is my strength.” יהוה אדני חילי “Iod-Hei-Vav-Hei Adonai is my strength.”

At the bottom of this image you see the Hebrew letters Aleph, Daleth, Nun, and Iod which form the word אדני Adonai. The word Adonai means “my Lord” in Hebrew. Adon is lord. Adonai or Adony means “my Lord.” Adonai is another Tetragrammaton or “four lettered name.” The Conjuration of the Four addresses the Tetragrammaton. Tetra means “four” and gramma means “graphic or letter.” Tetragrammaton therefore means the “four lettered name of God,” which we always state is יהוה Iod Hei Vav Hei, yet here we also say it is Adonai or Adony, since Adonai also has four letters, namely Aleph, Daleth, Nun and Iod. In other words Adonai is another Tetragrammaton or another Tetragram.
So the Tetragram אדני Adonai relates to the world of Malkuth, which is symbolized by a cross in the middle of a circle. The cross relates with the four elements, with the four cardinal points. These elements in alchemy are salt, sulfur, mercury, and azoth.
