When a person wishes to unify the Blessed Holy One and His Divine Presence (the male and female aspects of the Divine), he must banish all other thoughts. [Such thoughts] are the Klipot, regarding what is written, “There are many thoughts in the heart of man” (Proverbs 19.21). One must bring the Divine Presence into his mind, as the verse continues, “But the counsel of God will abide.”
This is the mystery of Unification. The individual who is worthy of the World to Come must unify the name of the Blessed Holy One. He must unify the upper and lower levels and limbs, uniting them all bringing them all to the necessary place, where the knot can be bound.
This is the mystery of “Hear O Israel, God is our Lord, God is One.”
The mystery of “Hear” is the Name which becomes seventy names.
This is the unifying category, Israel. It is called the Elder Israel, since there is also a lesser [Israel]. Regarding [the latter] it is written, “Israel is a child and I will love him” (Hosea 11.1). But [the one alluded to in “Hear O Israel] is the Elder Israel.
[This Elder Israel is] a single mystery and a single unifying category. “Hear O Israel” thus includes the [supernal archetype] Female and her Husband.
