成唯識論述記 1.632

1.632

述曰：不許，違理者：謂若不許得此，即得彼，即違彼、此是一體之比量理也。若許，便違世間之事。進隨自宗得，違事不成；退隨他不得，違理不成。此即近結。若遠結者，進從於他，便違自教；退隨自教，有違理失。故是所執，進退不成，但是妄情所計度也，結歸唯識。

The Commentary states: 'If you do not accept this, it contradicts reason' means: if you do not accept that reaching this entails reaching that, you contradict the reasoning of the syllogism that 'that' and 'this' are of one substance. If you do accept it, you contradict worldly affairs. If you advance following your own school to accept [reaching], you contradict worldly affairs and it is unestablished; if you retreat following others to not accept it, you contradict reason and it is unestablished. This is the immediate conclusion. As for the broader conclusion: advancing to conform with others contradicts your own teachings; retreating to follow your own teachings incurs the flaw of contradicting reason. Therefore, what you posit fails whether you advance or retreat, and is merely conceptualized by deluded sentiment. This concludes by returning to vijñapti-mātra.
