The Book of Zohar, Chapter “Truma [Donation],” Item 217: The soul of every living thing” is a soul that exits the One who lives forever, Yesod de ZA. And because he is His, for all the blessings come forth from Him and are in Him, and He waters and blesses below, toward Malchut, this soul that comes forth from Him has permission to bless this place, Malchut.
Malchut is the desire that every time takes on new forms in its intention to bestow, and then it feels that it becomes filled by Yesod. This means that Malchut becomes similar to Yesod according to the law of equivalence of form. In reality, it becomes like the first nine Sefirot because Yesod comprises all of the nine Sefirot.
When Malchut resembles the first nine Sefirot, it signifies that the creature becomes similar to the Creator to some degree. To the extent of similarity between them, to the extent to their similar properties, Malchut obtains the same form as the first nine Sefirot and exists in adhesion and oneness with them.
