第四釋住門中。言漸入滅定者，若慧解脫人欲入無餘時未必入滅定。今約俱解脫故說先入滅定，亦可羅漢將入無餘時要入滅定，不須出定遂入無餘，此則住於第八識入般涅槃，不同小論住第六異熟心等而般涅槃。

Fourth, in the section explaining the portal of abiding: Regarding the statement 'gradually enters the concentration of cessation', if a person liberated through wisdom wishes to enter [nirvāṇa] without remainder, he does not necessarily enter the concentration of cessation. Here, it is said that one first enters the concentration of cessation with reference to one who is doubly liberated. Alternatively, when an arhat is about to enter [nirvāṇa] without remainder, he must enter the concentration of cessation, and without having to emerge from the concentration, he immediately enters [nirvāṇa] without remainder; this means abiding in the eighth consciousness and entering parinirvāṇa, which is different from the Hīnayāna treatises [which hold that] one enters parinirvāṇa abiding in the sixth vipāka-mind, and so forth.
