There’s no place in the mind for seichel (logic) and for shtus (foolishness) to be together. When you fill your mind with chachma (wisdom), then the foolish attitudes of the world, sinah and kinah (hatred and jealousy), will go out.
Of course there’s always some kinah... No matter if you’re a tzaddik, you see another tzaddik standing a longer Shemoneh Esrei, it hurts you. You’d like to do the same thing too. That’s good, very good. — Nachas From Children (#E-120)
