4.125

Regarding "marks are, etc.": this means the thirty-two marks are merely reflected images appearing upon the mirror-like wisdom; since they fall into the category of the saṃskṛta, they are subject to change by the four marks. Moreover, their presence or absence varies depending on the capacities of beings; how could this be taken as the dharmakāya? Therefore it says that marks are saṃskṛta, etc.; this explains 'the physical marks spoken of by the Tathāgata' in the sūtra.
