According to Osho, as long as you feel “I am content,” a trace of discontent remains; true contentment is so total it forgets itself. This selfless contentment is identical with real happiness—the saint’s natural state—where the play of “happy/unhappy” no longer arises. Unhappiness signals inner un-saintliness (expectations, comparisons), not outer causes.
Real contentment is when you stop checking if you’re happy or sad; then a quiet, natural happiness stays by itself.
