The Supreme Mind first calculated how the creations should be in their unrectified state, i.e. that they should contain many parts of evil. In the worlds above, these are the governmental laws of destruction, which stand ready to destroy those very entities, and these parts were included in them. Afterwards He calculated how those same realms and beings were to be in a state of destruction and negation.
The evil components mixed up in them were to attack and gain power, bringing about their own destruction. On the level of the upper realms the existing entities are then seen to be broken, destroyed and negated because of the rule of the evil components over those entities themselves. Now, since these entities existed on the level of the upper world (that of the Sefirot) and were also destroyed, we see that they were indeed brought into existence in the mode of creation and destruction.
However, initially it was the force of destruction that took greater and greater control – which would not have allowed anything to exist at all. Afterwards the Supreme Mind calculated how these entities should exist in a state of repair, though not one of complete repair. They were to be rectified only to the extent that they are now: they are not in complete ruins – they exist – but they are damaged.
The measure and calculation of how existence is to be in this state constitutes the Sefirot as they are now, after the “balance” (משקלא, mashkela, “weight” or “scales” – Zohar, Terumah 176b). This balance is the key to the entire repair. (See Opening 59 Part 1 and Opening 69 Part 1.)
