Original Text
One who understands the Great Way knows all without stepping outside; without looking out the window, they perceive the patterns of nature. The farther one chases outward, the less they truly know. Thus, the sage knows without traveling, sees without looking, and accomplishes without acting.

"The farther one goes, the less one knows" means that sensory experiences from what one hears and sees are not reliable. Over-reliance on such sensory experiences can lead to confusion and doubt, preventing a deep understanding of the essence of things and a clear grasp of their entirety. The sage understands all things in the world not merely through sensory perception but through inner introspection, by achieving a state of emptiness, tranquility, and simplicity in the mind to observe all things and grasp their developmental laws, which is the "Way." Thus, one can know the Way of Heaven without going out the door and understand the principles of Heaven without looking out the window.Analysis
In this chapter, Laozi starts from the idea of "non-action" and presents his own "epistemology" and "practical theory." Epistemologically, the worldly method is to broaden one's knowledge through extensive experience, while Laozi's method is to "attain the One" and "hold the One as the standard for the world," grasping the overarching principle of the Dao, so that without leaving home, one can roughly understand the affairs of the world. Practically, it means acting in accordance with the Dao without subjective or arbitrary interference, thus appearing to do nothing yet achieving success—this is "accomplishment through non-action."
"Without leaving his door, he knows the world; without looking out his window, he sees the Way of Heaven. The farther one goes, the less one knows." "Door" means the entrance to one's home. "Knows" refers to understanding the true nature of the world. "World" means the entire reality. "Way of Heaven" means the natural law, the principle of how the world arises and develops. Laozi believed that one who understands the great Way does not need to go out to infer the principles of the world; without looking out the window, one can understand the laws of nature. From this statement, we can see that Laozi did not value external experience but highly valued inner intuitive insight. He believed that the mind is originally clear and transparent, like a mirror, inherently possessing the ability to perceive external nature and penetrate the real world. Here, "knows the world" and "sees the Way of Heaven" are subjective understandings achieved under the premise of following "non-action." In previous chapters, Laozi repeatedly emphasized that the virtue of the Way is without desire or seeking, and the sage aligns with the virtue of the Way because they achieve non-contention and non-action. The sage knows that all things in the world originate from heaven and earth and nature. The great Way is non-active, the Way of Heaven is non-active, and so are the human way and the way of things.
"The farther one goes, the less one knows." "Goes" means leaving home. This saying means that the more one rushes outward, the less one truly understands. How to grasp its meaning? Actually, Laozi wants to tell us that if the mind's activity chases outward, it leads to chaotic thoughts and scattered spirit, like dust covering a mirror—this is "the farther one goes, the less one knows." Laozi believes that one should strengthen self-cultivation, abandon desires, clear the mind's obstacles, and use open wisdom and a tranquil heart to observe external things and understand the laws of their operation.
Therefore the sage knows without traveling, understands without seeing, and achieves without acting. "Traveling" refers to leaving home and going far away. "Acting" means people's deliberate cognitive efforts, that is, reckless action and purposeful action. Laozi finally points out that it is precisely for the preservation of life's essence that people's blind actions must be resolutely rejected. He believes that the greater the scope of action, the less true knowledge is gained. A true wise person need not take great actions to acquire correct knowledge.
