金剛三昧經論 3.193

3.193

論曰：此下第五懺悔流通。於中有二：先讚懺悔功德、二者往復重顯。初中言清涼者，滅不善因沈濁故清，離生死果熱惱故涼。

The treatise says: From here down is the fifth, propagation by confession and repentance. Within it there are two parts: first praising the merit of confession and repentance, and second reiterating it through question and answer. In the first part, regarding 'coolness': it is pure (qing) because it extinguishes the turbid foulness of unwholesome causes, and cool (liang) because it frees one from the burning torment of the fruit of birth and death.
