According to Osho, nothing makes him unhappy or most happy; he lives in bliss, which is beyond the mind’s swings of happiness and unhappiness. Those moods depend on external causes, while bliss arises from being centered in one’s own being. When rooted within, serenity and joy abide, and happiness/unhappiness fade as distant, meaningless echoes.
Happiness and sadness come from outside things, but real peace comes from inside when you rest in yourself.
