Unity of Heaven and humanity
In Daoism, the concept of Tian or "Heaven" is viewed as nature, and humans are considered to be a part of nature. The saying goes, "If there is man, there is also heaven; if there is heaven, there is also man." This belief reflects the idea that heaven and earth are interconnected and all things in the world are unified. As the philosopher Zhuangzi stated, "Heaven and earth were born with me, and all things are one with me."
