Newcomers find the routine [at the Sabarmati Ashram] a stiff business, but we are trying to live the life of the billions of the earth. They are toilers all the day long. They have to do their thinking whilst their bodies are working. When the routine becomes natural, it becomes pleasant and does not interfere with hard thinking. All thinking is not useful. Clear thinking is the need. That can only come through continuous sacrifice,
i.e. toiling for the service of others (March 1, 1933).
