From looking at many people’s lives, we often see that they are almost like rudderless boats. They’re just tossed here and there. There is no direction for them. Even a small wind can toss them here and there. And to such people it’s very, very difficult to say when they will reach their goal, and how. In Yoga it’s the same. We must always keep the goal clear and see that our every action is recorded, measured, limited and controlled. Every one of us must become navigators. The body is like the boat; inside is our common sense, and our intelligence is the navigator.
