From The Study of the Ten Sefirot, Part 6, “Inner Reflection,” Chapter 7: The thinning of the screen does not effect the desires nor create any changes in them. The desires remain with the same depth as they were before the weakening of the screen.
Therefore, we never attempt to correct the desire itself: its depth (Aviut) doesn’t change, only the screen changes. Our inherent qualities will never change. The qualities you were born with, both good and bad, will remain with you always.
The personality you had as a child will remain unchanged until old age. A person simply learns through out his life which qualities to implement and to what degree. However, all of his inherent qualities are forever embedded in him.
We only correct the implementation of our qualities, desires, and inclinations. We have to bring each quality to its maximum use while preserving the natural balance between all of our qualities and desires. After all, there is “no coercion in spirituality.” The only thing is that we have to use all of them to bestowal to our fellow man and through that to bestow to the Creator.
