御注金剛般若波羅蜜經宣演 2.152

2.152

經。何以故至如來度者　演曰。三徵四釋。釋中有三。初順成次返顯後簡異。此初也。真如理中一相不存。若依俗諦但有五蘊無實眾生。以天我故無實可度。依彼論解如次前引問。設謂實有而生度想有何過失而遮止耶。

Sūtra: “Why? […] who are crossed over by the Tathāgata.”
Exposition: Three, inquiry; four, explanation. Within the explanation there are three: first, direct confirmation; next, counter-demonstration; later, setting apart differences. This is the first. In the principle of tathatā, not a single mark remains. If according to conventional truth, there are only the five aggregates and no real sentient beings; because of being devoid of self, there is no real entity to be crossed over. Relying on the explanation of that treatise, it is as quoted immediately above. Question: If one supposes they really exist and gives rise to the thought of crossing them over, what fault would there be that it is prohibited?
