A man of gladness seldom falls into madness.

The saying links a cheerful, contented disposition with steadiness of mind. It suggests that habitual joy can make a person less vulnerable to despair, agitation, or loss of self-command.

Its force is preventive rather than absolute: “seldom” allows that happiness does not guarantee mental health. The archaic word “madness” can stigmatize mental illness, so the proverb should not be read as medical advice, a cure, or a judgment on people in distress.

Use it as a reflective observation about the stabilizing value of cheerfulness or emotional resilience. In contemporary settings, avoid directing it at someone in mental-health crisis, since its contrast between gladness and “madness” can sound dismissive or stigmatizing.
