Yesod (Kabbalah)

The sefira of Yesod is the ninth of the ten sefirot. When the sefirot are divided into the five primary sefirot – Keter, Ḥokhma, Bina, Tiferet, and Malkhut – Yesod is encompassed in the sefira of Tiferet. Yesod is the sefira that represents the end of the middle line or column, the line of Tiferet. Accordingly, Yesod is a unique aspect of the sefira of Tiferet and also exists in parallel in the sefira of Malkhut, which receives the lights of Tiferet. Yesod, which means “Foundation,” is named thus because it includes the “foundations” of its level, meaning the various lights within that level. It then transmits these lights to the sefira of Malkhut below it, so that Yesod serve as the foundation for the existence of the feminine aspect of the level. In the structure of partzufim, which correlate to the human body, the sefira of Yesod represents the sexual reproductive organs.
