Rabeinu tells us that one must get rid of the trait of victory/strife/war (always having to win) and chase after the trait of peace, which is the only suitable vessel to contain all the blessing of the Jewish People (as it says in the Mishna of Masevhet Uktzin 3:12). One who makes peace draws people close together and raises the Feminine Waters.
Rabeinu also talks about how to elevate the sparks which fell at the beginning of creation. How? Through speaking words of Torah and Tefilla/prayer. This also allows a person to refine the blood that he has yet to serve G-d with, and make peace!
Look into the lesson for more about fear, negating the body, etc…
