維摩經玄疏 5.88

5.88

答曰：若觀真諦之理，發於真智，即生滅之智，故此經淨名訶迦旃云：「無以生滅心，說實相法。」若見中道之理發智，即是無生滅智，故《大涅槃經》云：「諸佛所師，所謂法也。以法常故，諸佛亦常。」諸佛亦常者，即是無生寂照之常智也。

Answer: If one contemplates the principle of absolute truth and gives rise to absolute wisdom, this is wisdom of arising and ceasing; therefore, in this sūtra Vimalakīrti rebukes Kātyāyana, saying: 'Do not explain the dharma of the true mark with a mind of arising and ceasing.' If one perceives the principle of the Middle Way and gives rise to wisdom, this is wisdom without arising and ceasing; therefore the Mahāparinirvāṇa Sūtra says: 'That which the buddhas take as master is the Dharma. Because the Dharma is eternal, the buddhas are also eternal.' That the buddhas are also eternal is precisely the eternal wisdom of unarisen quiescent illumination.
