“The feminine power in the divine world, best known by the name shekhinah (divine residence) … is the tenth and lowest power in the divine realm, and therefore closest to the material, created world and to human beings. She is the divine power that is envisioned by the prophets, and after their death the righteous reside in her realm. As the lowest sefirah she is closest to the sufferings of the people of Israel, and is most exposed to the machinations of the evil powers, who constantly try to establish dominion over her. Being feminine, she is the weakest among the divine powers, and the satanic forces can achieve a hold and draw her away from her husband (the male divine figure, often the totality of the other nine sefirot, or, sometimes specifically the sixth sefirah, tiferet), thus disrupting the harmony of the divine world. She is dependent on divine light, which flows from above; she is like the moon, which does not have light of its own, only the reflection of the sun’s light.”
