זוהר שמות — דף רנו ע”ב

From the seventh palace begins the unification of all mysteries and grades. Everything is one and forms a single union to properly unify the Holy Name. Supreme abundance flows into this palace to illuminate all the worlds. This palace is the mystery of the parasha Pekoudei, crowning the inner Tabernacle and divine service. From here emerges the mystery of perfect divine unity across the generations of the world.
