金剛般若經依天親菩薩論贊略釋秦本義記卷上 1.58

1.58

經。何以故　自下第二重成也。文中有二。先徵後釋。此初徵也。徵之意者。先離我相已成證淨。更離法相其故何耶。

[Sūtra:] "Why is this?" From here on is the second, re-establishing. In the text there are two parts: first, an inquiry, and next, the explanation. This is the initial inquiry. The intent of the inquiry is: having previously been freed from the notion of a self and having already accomplished realization and purity, what is the reason for further being freed from the notion of dharmas?
