…while a created realm was to be brought into being… The Other Side is not like the Sefirot, which, being the attributes of the Supreme Will, are actual Godliness. This is not so in the case of the Other Side, which is a created realm brought forth by the Supreme Will just as He brought all the other creations into being out of nothingness.
…that would involve every kind of defect and lack of goodness... This is what is meant by the verse, “God made also this one against this one”. The intention was to make the good and to make everything that can be the opposite of good: every kind of damage and destruction. The many different levels of the Other Side correspond to all the many different kinds of damage and destruction that can exist when there is deficiency in the world.
