金剛經纂要刊定記 4.117

4.117

舉疑因。經意云：於汝意中，還可用三十二相之身見法身如來，為不可耶？此相是疑起之因，故舉以問。

Raising the cause of doubt: the sūtra's meaning is: 'In your opinion, can the dharmakāya Tathāgata be seen by means of the body with thirty-two marks, or not?' These marks are the cause of the doubt arising, so they are raised to question him.
