金剛三昧經論 2.55

2.55

The treatise states: The three verses below do not versify distinct passages, but are merely a general praise. In this there are four: doctrine, simile, application, and conclusion. This is the first, the doctrinal statement, praising that "explaining now what had not been explained." Although it was previously explained at length, now in this sūtra the words are concise yet the meaning is rich, the text is succinct yet the principle is detailed; because such subtlety had not been previously taught.
