The fourth inquiry is: The sitra aḥra [the “Other Side,” the forces of evil] and the kelipot [“husks,” a kabbalistic expression for negative aspects of reality] are unimaginably distant from God’s sanctity. How, then, could these emerge and come into being out of God’s sanctity?! Could it be that God’s sanctity actually exists within them?!
