And Baal HaSulam said that wherever the sages say that it is forbidden, it means that it is impossible. Since “the Torah only exists in those who kill themselves for it,” which means that a person annuls his “self” and wants to annul before the Creator, and then the Creator gives him the Torah as a present.
Therefore, a person should know that the Creator has chosen only the phase of Israel in a person, and it is only with regard to this phase that it is written, “You have loved us and wanted us.” Thus, a person who says, “You have chosen us,” must respect and regard the phase of Israel in him and annul all the other desires of the nations of the world in which he is incorporated.
We must make sure that the qualities which bring a person closer to spirituality are always prominent and speak within him, whereas all the other qualities should be repressed. Then, a person’s inner structure becomes similar to the spiritual Partzuf in the attributes that he receives from the environment. It is only in them that he can receive the Torah since they are the desires that were made as a result of the connection, the bestowing desires that stem from unity.
However, if these are a person’s own attributes, then they certainly will be egoistic. He never will be able to feel the truth in them and, so, it is impossible to advance by them.
If a person makes a decision that only the desires that he receives from the environment are the desires of his soul, he understands that it is impossible to advance any other way and that everything in him except for that spark is crooked (in Hebrew “crooked” sounds like “idol worshiper”) and not straight. This way a person arrive at the formation of the right vessel in him by understanding that all his personal desires are flawed.
