Let’s delve now into the very esoteric Petach 16 which cites the fact that the Sephirot express two sorts of “forward” and “backward” light. Firstly, after the descent grade by grade from Keter to Malchut, Malchut then turns backward to become Keter, and so on in the same way until Keter becomes Malchut.
That’s to say, Sephira #1 (Keter) emanates from Starting Point A in the spherical Empty Space created by the Tzimtzum (to be explained later). Sephira #1 then irradiates downward through the spherical Empty Space (which is obviously no longer empty) to produce (spherical) Lights #2, 3, 4, (Chochma, Binah, Chessed, etc.) until it reaches End Point A of the spherical Empty Space, where it produces Light #10 (Malchut). Then the whole thing repeats itself in reverse.
Light # 10 (Malchut) starts ricocheting back from new Starting Point B (i.e., the old End Point A) in the spherical Empty Space so that Light #10 (Malchut) now functions as a new Light #1 (Keter) until it becomes a new Light #10 (Malchut) at new End Point B (i.e., the old Starting Point A). Then the whole process repeats itself.
But there’s more.
