The Torah Develops the Recognition of Evil in a Person
The beginning of one’s work ["Avodat HaShem" – "the work of the Creator" in order to become similar to Him] is the recognition of evil. This means that a person asks of the Creator to feel how bad he is, meaning the will to receive. Knowing it—that the will to receive is called “evil”—is something that only the Creator can make him feel. This is considered that through the Torah, one can achieve recognition of evil, meaning to know how evil the will to receive is. Afterwards, he can ask for the will to receive to be replaced and to be given the desire to bestow in return for it.
