47. The second level of brains of maturity is the seven lower sefirot of Bina that were established in Yisrael Sabba and Tevuna and require Ḥokhma in order to transmit the light of Ḥokhma to Ze’er Anpin and Nukba (as stated in section 43 above). Accordingly, at the phase of maturity, the yod exits from the avir of these seven lower sefirot, and the light of Ḥokhma returns to them in order to give to Ze’er Anpin and Nukba.
However, Yisrael Sabba and Tevuna do not receive Ḥokhma for themselves either, since they are of Bina, and all of Bina, whether the first three or the lower seven, is from the light of giving.96As explained in the previous sections, Yisrael Sabba and Tevuna is partzuf of the seven lower sefirot of the level of Bina of Arikh Anpin, which is the first partzuf of the world of Atzilut. The entire level of Bina of Arikh Anpin, the first three mentioned in the previous section, the first level of brains of maturity, and the lower seven mentioned here, do not receive the light of Ḥokhma.
This is because Bina only contains the light of giving. Bina still serves to transmit the light of Ḥokhma to the lower levels of Ze'er Anpin and Nukba. See section 36 and subsequent sections for a more complete explanation of the relationship between Yisrael Sabba and Tevuna and Ze'er Anpin and Nukba.
