Sleep and do not sleep; eat and do not eat; walk and do not walk; speak and do not speak. This means: if you sleep every night, sometimes do not sleep; if you eat every day, one day in seven do not eat; or if you eat all month long, one or two days in the month do not eat. This gives a mastery that you cannot gain by renunciation alone. It does not mean that you should starve. The body must be given good food, fresh food, and all its needs must be satisfied. This is better than that it should always long for what it sees before it. You must give the body what it needs, but you must control its needs, and not be controlled by them.
