金剛三昧經論 3.44

3.44

經曰　「善男子！如彼諸禪觀，皆為故想定，是如非復彼。何以故？以如觀如實，不見觀如相，諸相已寂滅，寂滅即如義。如彼想禪定，是動非是禪？何以故？禪性離諸動，非染非所染，非法非影，離諸分別，本義義故。善男子！如是觀定，乃名為禪。」

The sūtra states: "Good man, those various dhyāna-contemplations are all concentrations of past conceptualization; this thusness is no longer those. Why is this? Through thusness one contemplates real thusness, and does not see the characteristics of contemplating thusness; all characteristics are already extinguished, and extinction is precisely the meaning of thusness. Is not a dhyāna-concentration conceptualized like that movement rather than dhyāna? Why is this? The nature of dhyāna is free from all movement, neither defiling nor defiled, neither dharma nor shadow; it is free from all discriminations, because the original reality is the real. Good man, contemplation and concentration such as this is truly called dhyāna."
