To be in a state of Lo Lishma (for oneself) means to know what Lishma (bestowal) is. We cannot make judgments about any quality if we have not attained its opposite. That is why we have to feel to some extent what Lo Lishma and Lishma are, in order to assess in which state, relative to these, we are.
All of the Lo Lishma steps begin with the moment a person imagines himself to be in the upper Light, in the absolute quality of bestowal, but he does not feel this quality because his own qualities are not yet corrected and they conceal the true perception from him, meaning that they conceal the Creator from him personally. Then, a person says that he is located in Lo Lishma, in egoism.
He can say which qualities in particular are concealing the Creator from him during each moment, at any given opportunity. He is like a child who is perceiving life on the level of a two-year-old or a ten-year-old.
In other words, we have to imagine what bestowal is. We may not perceive it yet in its true sense, but we already feel that we are located opposite to this quality, besides which there is nothing.
However, in our perception of reality, we see our own dark qualities, opposite to bestowal, that draw us such a picture, all kinds of forms against the white background of the quality of Bina, the property of bestowal. This picture, the level of concealment from us of the quality of bestowal, is called this world. On the other hand, this world “covers” (compensates for) my imperfections and conceals them from me, and I am able to exist behind this concealing screen.
The Creator simultaneously reveals and conceals Himself from us, and we need to take this example from Him and clarify both of His qualities: His revealing Himself to us and His concealing Himself. That is, there always exists some kind of revelation and concealment called the “screen,” “covering,” which conceals and at the same time adds and compensates.
