Abstract: As a distinctive Buddhist idea, the "mutual use of the six roots" subverts the traditional concept of each senses playing their respective function, and brings new aesthetic concept and theoretical guidance to Song Dynasty poetry creation, especially the scent poetry、poems on paintings、dietetic poetry. It makes Buddhist names such as nasal view, ear vision, eye hearing and tongue meditation enter into the aesthetic field of literary, marks the Buddhist brand of meditation and enlightenment for synesthetic writing, and sublimates the physical sensory experience into the the mutual integration of the spiritual realm and the thoughts of Zen enlightenment.In addition, scholars in the Song Dynasty often avoided the assumption that there was little difference between the senses in the Buddhist thought of the "mutual use of six roots", and demonstrated or tended to demonstrate the uniqueness of a certain root alone, such as the emphasis on smelling incense and meditating on the nose. This is not consistent with the basic spirit of Buddhism, which is the "mutual use of six roots", but it is closely related to the aesthetic interest of the Song Dynasty, which is to worship "meaning" and "rhyme".
