Cantico dei cantici 6:11 Cabala: Pri Etz Hadar & Zohar

From this you can understand that although the blessed Creator rules over the earth and everything has an angel assigned to it, nevertheless of greatest importance is the fact that everything is connected to the supernal attributes.²⁹I.e., the sefirot.

This is the garden that went forth from Eden and it is the Shekhinah.³¹The tenth sefirah, Malkhut.

It is located under the tenth sefirah. the four tributaries that spread out from the garden like a nut . . .”³³Zohar, ibid. From this we can infer that herbs can be distinguished by the pre-eminence of their divine roots above.

King Solomon penetrated the depth of the secret of the nut, as it is written: "I went down into the garden of nuts" (Shir Hashirim 6:11). He took hold of the shell (Kelipah) of the nut and looked at all its layers. He came to realize that the main pleasure of the spirits in the shell of the nut was just to cling to human beings and defile them, as it is written: "And the delights of the sons of men, women very many (Heb. שִׁדּוֹת)" (Kohelet 2:8). This means that the demons (Heb. shedim) take pleasure only in human beings.
