金剛般若經依天親菩薩論贊略釋秦本義記卷上 1.43

1.43

經。如來所說身相即非身相　第四釋也。身相是妄相法身名實相。妄相非法身名相即非相。

[Sūtra:] "The bodily marks spoken of by the Tathāgata are not bodily marks:" The fourth part is the explanation. Bodily marks are false marks, whereas the dharmakāya is called the real mark. False marks are not the dharmakāya, so it says that marks are non-marks.
