You must now understand something that was introduced after the Tzimtzum: this is the Line of Measurement (קו המדה, kav hamiddah, also known as בוצינא דקרדוניתא, boutzina d’kardunita, the “torch of darkness”). This is the power to institute boundaries, which causes lack and deficiency. For the Tzimtzum brought into being something that did not exist at first – deficiency. Initially all was perfection, and it was only afterwards that deficiency emerged. Here we have the underlying power of Judgment, which was revealed through the Tzimtzum. This is the power that causes concealment, void and emptiness, bringing about every kind of deficiency that can possibly exist, as we actually find in reality.
