Chih-i brings forth a critical theory of good and evil, which is based on the principle of True Reality that the Dharma-realm is of no distinction, and that good and evil are of the same reality, in a sense, good contains evil and evil contains good. In the phenomenal world, what appears to be good may be evil as it may attract evil result; and what appears to be evil may bring good result. Good and evil are only relative, and they can never be absolute as long as there is a distinction between them. Only when what one refers to as so-called good and evil are conceived as one identical entity, can one reach the absoluteness of the True Reality. This is true in spite of the fact that in the course of time and space, there appear to be dual aspects called “good” and “evil” in the eyes of ignorant people. (Vol. 2, Page 260)
