It comes from "Heaven moves vigorously, a gentleman should constantly strive for self-improvement", from "The Book of Changes·Qian Gua".
"As heaven moves forward, a gentleman should constantly strive for self-improvement"? That is: as the development of objective things, with its "newly built" character, it moves on its own, and the great road emerges naturally. A truly knowledgeable "gentleman" should know the time of heaven, follow the destiny of the time, comply with the natural laws of "the way of heaven", and promote the movement and development of such objective things with the spirit of "heaven" of "continuous self-improvement", so as to achieve the goal of "heaven and man". "unity" state. This character of "continuous self-improvement" is the "unity of subject and object", that is, it is based on the ancients' objective observation of "Heaven" and endows it with the character of a gentleman. This philosophical thought is the philosophical wisdom of "the unity of things and myself".
