A Professional Soldier
We all want to come to the level where we no longer experience certain thoughts and desires and are free to deal with other challenges. However, it is very possible that we will never reach that point, that we are by nature beinonim who must engage in this struggle our entire lives.
A beinoni is a professional soldier. He was not created to live in a safe, protected haven. Rather, his job is to battle on behalf of
G-d, overcoming the sitra achra within himself.
(Rabbi Adin Steinsaltz)
