The descent of the worlds from top to bottom is built in such a way that due to its actions, the creation increasingly reveals its Master’s attitude toward it. It seems to be in the process of research. In the spiritual world, it is impossible to search for answers with our rational logic—we must penetrate it sensorially and then we will understand more. Then, from our sensations, we can find an explanation in our reason.
Imagine that I am standing in front of the Master with my desire to enjoy and now I reveal His attitude toward me at a certain level. I begin to work with it; I reject this pleasure, and make clarifications. At the same time, my desire is developing and refining after the spiritual action I have made, and so I suddenly feel that the Creator has done much more for me than I previously thought. It seems that I have grown up and realized it, similar to how, after becoming older, a child justifies his parents for what they demanded of him.
Then, my screen is reduced; I can no longer stand up against what I had managed before. It would seem that the screen should have grown because I understood more. But this is not what happens and I feel that I can do nothing but annul myself before the desire of the upper one.
I reveal the growing love of the Creator toward me and my inability to respond to Him in the same way. Therefore, all the degrees of the descent of the worlds (Olamot) are called the degrees of concealment (Alamot). The creation has no way out; it blocks itself with screens, hiding the upper light and the Creator’s attitude toward it in order to hide behind them and somehow survive. These are not degrees of honor, but rather degrees of weakness. All this is happening not at the expense of the creation, but at the expense of the Creator who is building a spiritual vessel.1
