Now there first emerged the right line of Yisrael Sabba and Tevuna, which is Keter and Ḥokhma of Yisrael Sabba and Tevuna. This line was formed when the Malkhut of Yisrael Sabba and Tevuna ascended to the Bina of Yisrael Sabba and Tevuna. This caused the level of Yisrael Sabba and Tevuna to terminate under Ḥokhma, causing Bina, Tiferet, and Malkhut of Yisrael Sabba and Tevuna to fall below to the level of Ze’er Anpin (as stated in section 21 above). The two vessels of Keter and Ḥokhma, which remained in the level of Yisrael Sabba and Tevuna, became the right line, as stated above. Since there are only two vessels there, Keter and Ḥokhma, they contain only the two lights of nefesh and ruaḥ, while the first three are lacking (as stated in section 26 above).
