We have here two things. There is the Other Side (Sitra Achra), which is the opposite of what is rectified – this is what was rejected and expelled from the Sefirot. Then there is what remains of the kings that has not yet been purified. The Other Side is something that was allowed to exist but was nevertheless rejected and cast aside so as not to destroy the rest of existence. However, it did not pass from the world. It just does not destroy everything now as it did at the time of the initial destruction. Nevertheless, it stands ready and waiting to be aroused at its ordained time and within its ordained limit.
