摩訶止觀 2.12

2.12

觀貪欲瞋癡諸煩惱，恒是寂滅行，是無動行，非生死法，非涅槃法。不捨諸見，不捨無為，而修佛道。非修道，非不修道，是名「正住煩惱法界」也。

Contemplate greed, anger, delusion, and all afflictions as constantly the practice of quiescence, the practice of immobility, neither phenomena of birth-and-death nor phenomena of nirvāṇa. Without abandoning views and without abandoning the unconditioned, one cultivates the Buddha path. Neither cultivating the path nor not cultivating the path: this is called 'correctly abiding in the dharmadhātu of afflictions'.
