Answer: The soul. If a person, while correcting his egoistic desires, has created from them a likeness of the Creator, then such a state of desire is called “the soul.” More precisely, the soul is called the part of the desires that have become similar to the Creator. The term “Kabbalist” means a person who has such a desire.
Desire, first restriction, screen, reflected Light, coupling while striking, receiving for the sake of bestowal—that is the Partzuf, the soul.
