According to Osho, to have "enough" is to recognize the point where conceptual "nonsense"—even sacred talk like Zen—must be dropped. It signals a full stop: the end of verbal juggling and the beginning of silence and presence. Saying "enough" closes the debate and returns you from words to being—no more questions, just the immediacy of here-now.
It means stopping the talk and thinking because it’s time to be quiet and present.
