金剛般若經贊述 2.182

2.182

Asaṅga says: "'Different kinds of minds': one should know there are two kinds, defiled and purified, which are minds with desire, minds free from desire, and so forth." It records such minds of sentient beings because the Tathāgata knows them, and he instructs them all to sever evil and give rise to goodness, which is called the purification of cognition. The treatise states: "Cognition is established for the sake of teaching those various sentient beings tranquility of mind."
