Buddhism Sutra’s structure is basically “fusing Principle and Myth together”. According to “Myth -Idol”, there are two elemental kinds of annotation of Buddhism Sutra, one is explaining Myth by Myth, and the other is explaining Myth by Principle. Explaining Myth by Avenue is a special form of explaining Myth by Principle . Chen Ju, a scholar-bureaucrat in Nan Song Dynasty, wrote the comment of Vimalakirti-Nivdesa Sutra. Influenced by indigenous cultures such as Zhuangzi, the reeview was based on annotation of Zen and developed “Explaining Idol by Avenue ” and “explaining Myth by Principle ” to the extreme. Chen Ju argued that the figures of Buddha and Bodhisattva were symbolistic idols rather than objective ones. The kind of annotation was why Confucianism, Buddhism and Taoism could fuse into one.
