This ascent of Malkhut to Bina occurs in each and every level, from the beginning of the world of Atzilut until the end of the world of Asiya. There is no level that does not contain ten sefirot: Keter, Ḥokhma, Bina, Ḥesed, Gevura, Tiferet, Netzaḥ, Hod, Yesod, and Malkhut. The Malkhut that is in every level ascended to Bina in that level and was tempered there.
The Division of Each Level into Two Halves 16. It is known that Malkhut arrests the light of each sefira and every level. In other words, Malkhut arrests the light in the level from spreading into Malkhut itself. This arresting force derives from the force of the constriction that was placed on Malkhut, so that it cannot receive the supernal light. Therefore, the light of the level is drawn forth only up until Malkhut. When the light reaches the partition that is upon Malkhut it is arrested, at which point a fusion through collision occurs with the light on the partition that is on Malkhut (as explained in Petiḥa LeḤokhmat HaKabbala, section 14).
