Through involvement in the secrets of Torah and the reasons for the commandments, a person purifies the animal aspects of his desire to receive. Proportional [to that purification], he builds the point of his Neshama that is enclothed in him in the 248 limbs and 365 ligaments. When he becomes perfect in all of these, it [the point] becomes a Partzuf. Then, he rises and enclothes the Sefira of Bina in the spiritual world of Asiya.
This vessel is infinitely more pure than the first two vessels of Tiferet and Malkhut (TuM), and therefore it [the vessel] transfers to him a great light from Ein Sof, which is called the light of Neshama. All of the particulars of the inanimate, the plant, and the animal in the world of Asiya that are attributed to the level of Bina serve and assist in the Partzuf of the person’s Neshama, so that he can perfectly receive the light from the Sefira of Bina, as we explained in the discussion of the lights of the soul; see the discussion there.
