This article approaches Confucianism as a lost art of living and asks how we can make it relevant again for us. Central to this approach is the cultivation of heart-mind ("Xinxue," ??) designed to help cure ourselves of self-oblivion and self-centeredness so prevalent in our culture today. It is based on the idea of "Li" (?), the same as Spinoza's God, the absolute Being that has nothing to do with human aspirations at all. To seek this, "Li" is therefore to gain true freedom. Two preeminent Neo-Confucians of Joseon Korea, Yi Hwang and Yi I, discuss the method of "Jing" (?), paying full attention and being watchful, for that end.
