菩薩瓔珞本業經 2.33

2.33

「佛子！無生忍諸法，觀非有煩惱非無煩惱，一生一滅一果，三界最後一身一入一出，集無量功德，常向上地念念寂滅，故名遠行地。

"O Son of the Buddha! Having forbearance of the non-arising of all phenomena, contemplating neither having afflictions nor lacking afflictions, a single birth, a single cessation, and a single fruit, having the final single body in the three realms, a single entering and a single emerging, gathering measureless merits, constantly aspiring toward the higher grounds, cessation in thought after thought, it is therefore called the Dūraṅgamā-bhūmi.
