"The starting point, that first delight, the dot, could be anything in your experience. Suppose you are very thirsty, and you are presented with a glass of ice water. The first thought, or the dot, occurs when you hold the glass of ice water and you are about to drink, knowing that it is the real thing and 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 the idea, the connection, the first delight, the stroke is that 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. That is the concept of the stroke."
