Zrizus in Mitzvos: Why Enthusiasm Matters More Than Compliance

Rabbi Zweig opens with a difficult passage from Chazal: just as one must not delay making matzah (lest it become chametz), so too one must not delay doing mitzvos. The difficulty is stark—if delay in matzah produces chametz (an issur lo ta'aseh), then the parallel implies that doing mitzvos without zrizus (enthusiasm) is worse than not doing them at all. How can performing a mitzvah (מצוה) in a lazy manner be worse than omitting it entirely? The answer lies in understanding the psychology of resentment. When a person repeatedly does something he feels forced to do, he builds hostility with each iteration. Eventually this resentment explodes. A mitzvah performed without enthusiasm creates an inner rage that distances a person from Hashem (ה׳)—like chametz, it becomes spiritually poisonous. Not doing the mitzvah at all may be bittul aseh, but doing it with resentment creates active damage to the relationship.
