Meditation means being in the moment, not leaving this moment. Osho

Someone asked Buddha, ”How shall we meditate?”
Buddha replied, ”Whatsoever you do, do it with awareness; this is meditation. Walking, walk attentively, as if walking is everything; eating, eat with awareness, as if eating is everything; rising, rise with awareness; sitting, sit with awareness; all your actions become conscious, your mind does not travel beyond this moment, it remains in the moment, settles in the moment – this is meditation.”

Meditation is not a separate process. Meditation is simply the name for life lived with awareness. Meditation is not an hour-a-day affair where you sit for one hour and then it is over till tomorrow. No, if twenty-three hours are empty of meditation and only one hour is meditative, then it is certain that the twenty-three hours will defeat the single hour. Non-meditation will win, meditation will lose. If you are living twenty-three hours a day without awareness, and only one hour with awareness, then you will never attain to the state of buddhahood. How can this single hour triumph over the other twenty-three hours?

There is something else that also has to be understood. How can one be aware for one hour if in the remaining twenty-three hours one is not aware? How can you be healthy for one hour if you are sick the other twenty-three hours of the day? Health and sickness are the result of an internal flow. If you are healthy for twenty-three hours of the day, you will be healthy for all twenty-four hours, because the internal flow cannot suddenly be broken for just one of those hours. The current that is flowing goes on flowing.
