Craving is manifest in a variety of ways: it extends from simple egoism and selfishness to that deep-seated, anxious longing for security to fear of rejection by those we love to the compulsion to have a cigarette. Whenever such feelings arise, the habitual reaction is either to indulge them or to deny them. Which again blinds us to the phrase stamped on them by the Buddha: "Let Go!"
