When you are working in your office, I am not telling you to be a no-mind. When you are working in your shop or in the factory, I am not saying to be a no-mind. I am saying be perfectly a mind. Use the mind but don't carry it continuously, twenty-four hours, day in and day out, with yourself. Don't go on dragging it. Use it as you use a chair. You don't go on carrying your chair everywhere, wherever you go, just because you may need it.
