" The teachings of the Buddha are often grouped into two categories: the teachings on wisdom, or theory, and the teachings on method, or practice. The Buddha himself often compared these categories to the wings of a bird. In order to fly, a bird needs two wings. The “wing” of wisdom is necessary because without at least some idea of what you’re aiming for, the “wing” of practice flaps pretty much uselessly. People who go to the gym, for example, have at least a rough idea of what they want to gain by sweating on the treadmill or lifting weights. The same principle applies to the effort to directly recognize our inborn capacity for happiness. We need to know where we’re going in order to get there. "
