Musar על ברכות 9:7

This enables us to understand (Berachoth 5a): "If it is possible for one to study Torah and does not do so, the Holy One Blessed be He brings upon him sore afflictions which sully him, as it is written (Psalms 39:3): "I was dumb with silence, silenced from good [i.e., Torah] and my pain [i.e., my afflictions] sullied me." This is measure for measure. Because he shamed the Torah and made it like an unwanted vessel, he, too, was shamed before all.
