金剛三昧經論 3.78

3.78

經曰　佛言：「其智無窮。略而言之，其智有四。何者為四？一者定智？所謂隨如；二者不定智，所謂方便摧破；三者涅槃智，所謂除電覺；四者究竟智，所謂入實具足道。長者！如是四大事用，過去諸佛所說，是大橋梁、是大津濟。若化眾生，應用是智。」

The sūtra says: The Buddha said, “Its cognitions are inexhaustible. To speak of them briefly, its cognitions are four. What are the four? First is determinate cognition, which is called following thusness; second is indeterminate cognition, which is called skillful crushing; third is nirvāṇa cognition, which is called eliminating lightning-like awareness; fourth is ultimate cognition, which is called entering reality and completing the path. Elder! These four great functionings of affairs were spoken by the past buddhas: they are a great bridge, they are a great ferry crossing. If transforming sentient beings, one should apply these cognitions.”
