According to Osho, humans are unhappy because they carry an immense potential for bliss and feel the gap between that peak and their present valley; this very contrast hurts yet it is a blessing that drives evolution. Misery persists when we compulsively recreate it—clinging to familiar patterns and ideologies. Use unhappiness as a signal to change, seek, and ascend beyond mind-made suffering.
We feel sad because we sense we could be truly happy; use that feeling to drop old habits and climb toward your inner peak.
