He who sings frightens away his ills.

The saying expresses a folk-psychological truth: active, expressive joy (here, singing) can dispel or at least diminish suffering. “Frightens away” suggests that troubles are not always defeated by force or argument but by a change of spirit—music as a practical remedy for melancholy, fear, and worry. In a Cervantine register, the line also fits a broader humanist skepticism about solemnity: laughter, song, and imaginative play are portrayed as resources for endurance amid hardship. The aphorism elevates a humble act into a strategy of resilience, implying that emotional agency—choosing to sing—can interrupt the power that “ills” hold over the mind.
