In the Doctrine of the Mean (one of the Four Books in Confucianism), there is an important phrase that represents Confucius's main thought: 仁者人也 (rén zhě rén yě). See the following calligraphy I wrote. This phrase may be translated as "To love is to become the person." By the way, love (Ren in Chinese: 仁) appears frequently, 106 times, in the Analects of Confucius. The question is: What is Ren or love according to Confucius or how do we interpret it?
