肇論新疏 2.348

2.348

〈舍利品〉云：「菩薩行般若波羅蜜，知一切眾生，心亦不得眾生，乃至知者見者亦不得。」〈照明品〉云：「般若能照一切法，畢竟淨故。」〈三慧品〉云：「一切無所為，般若亦無所為」等。此中合集前後引之，以顯聖心知而又為，證權實不異也，兼證有知無知一致。

The "Śāri[putra] Chapter" says: "When a bodhisattva practices the perfection of wisdom, he knows all sentient beings, yet his mind does not apprehend sentient beings, up to not apprehending a knower or a seer." The "Illumination Chapter" says: "Prajñā can illuminate all dharmas, because it is ultimately pure." The "Three Wisdoms Chapter" says: "All is without doing; prajñā is also without doing," and so forth. Here they are collected and cited together to show that the sage mind knows and yet performs, proving that upāya and tattva are not different, and concurrently proving that having knowledge and lacking knowledge are identical.
