Unity of knowing and doing

知行合一，意指认识事物的道理与实行其事是密不可分的。知是指内心的觉知，对事物的认识；行是指人的实际行动。知与行的合一，既不是以知来合并行，认为知便是行，也不是以行来合并知，认为行便是知，而是内有良知则外有良行，知是基础、是前提，行是重点、是关键。知行合一是中国古代哲学中认识论和实践论的命题，主张人的外在行为是受内在意识支配，认为只有由衷向善做到“知”的人，才有外在自发的善“行”。

This phrase implies the close relationship between what one knows and what one does. "Knowing" refers to one's perception of the objects, and "doing" refers to one's actual deeds.

The unity of knowing and doing does not mean that knowing is doing and knowing can replace doing, or vice versa. It actually means that one should understand things correctly and act accordingly. Knowing is the premise, while doing is putting knowledge to work. The relationship between the two is an ancient Chinese philosophical topic. It is believed that one's conduct is controlled by one's conscience, and one will act properly on one's own initiative only if the true purpose is to do good.
