When you are practicing generosity, you should feel a little pinch when you give something away. That pinch is your stinginess protesting. If you give away your old, worn-out coat that you wouldn’t be caught dead wearing, that is not generosity. There is no pinch. You are doing nothing to overcome your stinginess; you’re just cleaning out your closet and calling it something else. Giving away your coat might keep someone warm, but it does not address the problem we face as spiritual practitioners: to free ourselves from self-cherishing and self-grasping.
