Ancient wisdom unites heaven and man for modern moral guidance.
The idea of Tian Ren He Yi, the unity of heaven and man, changed over time after the Song dynasty. Zhangzai promoted a moral cultivation method to counter Buddhism, Zhuxi linked political events to natural phenomena, and Lu Shi-yi emphasized the connection between heaven and man through Yin Yang Wu Xing. These different approaches all share a focus on reality and moral practice.
