Suppose you are very thirsty, and you are presented with a glass of ice water. . . . You hold the glass of ice water and you are about to drink, knowing that it is the real thing and that it will quench your thirst. Then holding the glass in your hand, you bring your arm close to your mouth, you bend your neck, you raise the glass and you begin to drink. Having had the idea, the connection, the first delight, . . . you proceed with the appreciation of that basic goodness. Strangely enough, when you are very thirsty, while you are drinking a glass of water, your mind is almost completely without anxiety at all. You can try this yourself. While you’re drinking a glass of water, you have no thoughts. You are purely synchronizing your mind and body together in drinking that nice cool glass of water.
