To return to our theme: Nukva needs the Five Strengths in her Yesod, these being the roots of the material substance of all the existing entities, as we have explained. When the material is renewed and duly repaired to enable Nukva to arouse this root in the proper way, the Receiver stands asking for Kindness from the Giver of Influence – and then the Male Waters will descend. However, in order to be able to arouse him, Nukva needs a power from the male that completes her, making her a receiving vessel. This power is the Spirit mentioned above. Everything is in the category of Strengths, for this Spirit is from the side of Strengths, because this whole function of sending the Female Waters is rooted in Judgment.
