The way of heaven is to diminish the superfluous and supplement the insufficient. Therefore, emptiness overcomes fullness, and insufficiency triumphs over excess. Its meaning is vast, its principles profound, and its implications deep. The phenomena of heaven and earth are divided, the signs of yin and yang are arranged, the causes of change are revealed, and the omens of life and death are clear. Without deliberate planning, the past actions align; without agreement, the bond between the visible and invisible is sealed. Examining their words reveals subtleties, and testing them against events shows no discrepancies. It can indeed be called the essence of the supreme way and the beginning of sustaining life. If the divine mechanism acts swiftly and recognizes the mysterious and interconnected, strategies may arise from innate knowledge, but standards also benefit from governance and instruction. There has never been an action that does not follow this principle or an outcome that does not stem from it. Thus, with focused effort and research, exploring the subtle and hidden, one may grasp the true essence, seeing the whole in parts. Hence, every movement brings success, as if guided by ghostly spirits. And thus, extraordinary heroes appear from time to time in the world.
