This is the mystical meaning of the statement “Three come out of one; one exists in three” (as explained in the Zohar, Bereshit 1, section 276, s.v. “ve’od,” and as explained in section 52 above). The three criteria for the process of fusion for the emergence of a lower partzuf have now been explained.
