According to Osho, laughter is uniquely human and essential: it is the antidote to boredom, which arises from our comparative, meaning-seeking mind. Wherever thinking deepens—civilized societies, higher intelligence—boredom intensifies, so laughter becomes more necessary. Thus it is not a mere phase but a life-supporting release needed throughout human life; without it, existence grows heavy, even suicidal.
We need laughter our whole lives because our thinking makes us bored, and laughing lightens that feeling.
