The entire Torah (correction of our egoism) serves a single purpose: to help us merge with the Creator. The purpose of positive commandments is to merge with the Creator through them. And all negative commandments relate to what separates us from the Creator.
– Avodat Israel, Pirkei Avot, Chapter 3
It is said (The Torah, Exodus 27:20): “And you shall command….” The word “command” (Tetzaveh) comes from the word “unity” (Tzavta). When you unite, you will become the head, and the Light of reason will be revealed in you.
