From the article by Baal HaSulam, “Introduction to the Study of the Ten Sefirot,” Item 68: We must know that all the inclinations, tendencies, and properties instilled in a person, with which to serve one’s friends, all these tendencies and natural properties are required for the work of God.
To begin with, they were created and imprinted in man only because of their final role, which is the ultimate purpose of man, as it is written, “he that is banished, be not an outcast from him.” One needs them all so as to complement oneself in the ways of reception of abundance, and to complement the will of God.
We need all the details of the relationships that unfold between friends. We should not retouch, cancel, hide, or suppress anything or prevent it from developing. All aspirations have to awaken, open up, and develop in everyone. Precisely these bad and good inclinations (no matter which one) with respect to the relationship of a person and his friend we afterward will have to turn into the relationship between a person and the Creator.
This is why the one who does not develop his relationship with his friend is not ready to become even one step closer to the Creator.
