As mentioned, a person acquires a Partzuf of Nefesh due to his involvement in Torah and mitzvot without proper intention. It is already enclothed there with a point of the light of Ruaḥ. As a person becomes stronger in Torah and mitzvot with proper intentions, the plant aspect of his desire to receive becomes purer. He builds the point of Ruaḥ into a Partzuf to the same extent [that he has become stronger in Torah and mitzvot].
By performing 248 positive commandments with proper intention, the point expands to his 248 spiritual limbs. By keeping the 365 negative commandments, the point expands to his 365 spiritual ligaments. When he perfects himself in all of the 613 limbs, he ascends to enclothe the Sefira of Tiferet in the spiritual world of Asiya, which transfers to him a great light from the Ein Sof. That light is called the light of Ruaḥ, which is focused on the purity of the vegetative aspect of the person’s body.
Every detail of the inanimate, plant, and animal aspects in the world of Asiya that are linked to the level of Tiferet assist the Partzuf of Ruaḥ in a person to receive the light from the Sefira of Tiferet, in all its perfection, as we explained earlier in the discussion of the lights of the soul [chapters 41–42].
