This poem, like that beautiful one, is different in principle in practice methods. Shen Xiu's song "No Love" made him lose the qualification of being a red man, but he became the founder of Beizong. Because Shen Xiu emphasized "being always clean", later generations called it "gradual revision school". Huineng's poetry is a complete denial of beauty, that is, subjective idealism is a complete denial of objective idealism, which directly grasps the key to "seeing nature as a Buddha" and is called "Epiphany School".
Huineng pointed out in the 20th section of the Tanjing: "Human nature is self-purification, and all laws are self-nature. To think of all evil things is to do evil; Think about all good deeds and cultivate them. " This is the basis of Huineng's epiphany theory. In his view, there is no insurmountable gap between "fools" and "wise men", "good people" and "wicked people", and between them and "Buddha". From "infatuation" to "enlightenment", it is only between one thought. This thought of "putting down the butcher's knife and becoming a Buddha on the spot" not only played a great role in the evolution of Buddhism in China, but also had a great influence on China's philosophical theory.
