大般涅槃經義記 3.36

3.36

「阿那含」者，此名不還。依如小乘，於欲界中更不受生，故名不還；若依大乘，不還起於愛佛煩惱，故名不還。位分何處？分別有三：一者守果，在第八地，愛佛煩惱此處斷故；二者攝因，四地已上同名那含，修習順忍向八地故；三者進向，上盡九地，合說後二為阿那含。以於此處同捨功用，供佛解義過前劣後，所以為一。

'Anāgāmin' is named here 'non-returner'. According to the Hīnayāna, one is no longer reborn in the desire realm, hence it is called non-returner; if according to the Mahāyāna, one does not return to giving rise to the affliction of attachment to the Buddha, hence it is called non-returner. Where is its stage located? In distinction there are three: first, maintaining the fruit, which is on the eighth bhūmi, because the affliction of attachment to the Buddha is severed here; second, including the cause, from the fourth bhūmi onward they are collectively called anāgāmin, because of cultivating the conformity-forbearance to advance toward the eighth bhūmi; third, advancing toward, extending upward through the ninth bhūmi. Combining the latter two, it is called anāgāmin. Because at this place they equally relinquish effort, and in making offerings to Buddhas and understanding the meaning they surpass the preceding and are inferior to the subsequent, they are therefore made into one.
