Through this power she sends up Female Waters… This is a particular power that enables the Shechinah to carry out this function of sending up the Female Waters.
…this being what she channels… This is the flow that the Shechinah for her part draws from the Emanator to send into the world. Its root is most exalted – for it lies in the Residue. The material substance of the separate creations derives from the Strengths in Yesod of Nukva – the root of Judgment revealed in the Residue. For as you have already heard, the Place that remained after the Tzimtzum is Malchut. The Judgment revealed therein is the Strengths in Yesod of Nukva, and this is the root of the material substance of the creations – “Everything was from the dust” (Ecclesiastes 3:20). The Line on the other hand is the Male Waters.
