These two forces in the partition operate at five levels, which are the four aforementioned levels of Ḥokhma, Bina, Tiferet, and Malkhut and their root, which is called Keter, each level representing a different measure of will to receive.
Admittedly, we explained that the first three levels are not characterized as vessels, and only the fourth level is categorized as a vessel, as stated above in section #5#. Nevertheless, the first three levels are the causes that lead to the completion of the fourth level, in such a manner that the fourth level, after its completion, bears the imprints of four different measures of the attribute of receiving that it contains,26As explained above, the fourth level, the level of Malkhut, was the end point of a process. During the course of that process, the other four levels – Keter, Ḥokhma, Bina, and Tiferet – each had a certain measure of will to receive, creating some measure of opacity and separation between them and the Creator, though considerably less than Malkhut’s will to receive. These other four levels of the will to receive, each with its own unique amount of opacity, are contained within Malkhut, since Malkhut is the endpoint in the process where the will to receive is incrementally differentiated from the supernal light, creating these levels, until it reaches Malkhut, which is comprised solely of will to receive. Therefore, the partition, positioned upon Malkhut, the ultimate form of the will to receive, can transmit one of the five qualitatively different types of opacity, one for each of the five levels mentioned here, and the returning light will be qualitatively different depending on the measure of opacity that rebuffs it. starting from the first level, which contains the most dilute measure of the attribute of receiving, followed by the second level, which is somewhat more opaque than the first level in terms of its attribute of receiving, and then the third level, which is more opaque than the second level with respect to its attribute of receiving, and finally the fourth level, whose own attribute is the most opaque of them all, as its attribute of receiving is complete in all regards. In addition, one should discern that the fourth level also contains the opacity (ovyut) of the root of the four levels, that of Keter, which is the purest of them all, since it contains a minute measure of will to receive.
