佛說仁王般若波羅蜜經 2.31

2.31

「復次，常現真實住順忍中，作中道觀，盡三界集因集業一切煩惱故，觀非有非無，一相無相而無二故，證阿那含位。復於九阿僧祇劫，集照明中道故，樂力生一切佛國土。

“Furthermore, the Bodhisattva of Constantly Manifesting Reality abides in the patience of compliance, engaging in the middle-way contemplation. Because they exhaust all the defilements of accumulative causes and accumulative karma in the three realms, they contemplate neither existence nor non-existence, the single characteristic that is without characteristics and non-dual, thereby realizing the anāgāmin position. Further, over nine asaṃkhyeya kalpas, accumulating the illuminating middle way, they take birth in all buddha-lands through the power of delight.
