According to Osho, laughter feels difficult because society has systematically repressed it, equating seriousness with respect and obedience. From parents to teachers to bosses, you were trained to suppress laughter, becoming 'laughter-blind' like colorblindness. Life itself is playful, not grave; if you unchain your laughter and give life a new orientation, everyday moments reveal humor, easing misery and transforming your inner climate.
You were taught to be serious, so you forgot how to see the funny side; relax and allow laughter, and you’ll start noticing joy everywhere.
