第三解修分齊遲速中，總有三類：一、極久遠者，聲聞極多經六十劫修解脫分善根，最後身般涅槃；二、非極久遠者，有經多生乃至一劫，方般涅槃；三、最極速疾得般涅槃者，要經三生。第一生中，發心修習解脫分善，謂五停心觀總別念處；第二生中，復修念處從總念處修趣煖頂，或入下忍，或入中忍名為成就。第三生中，復從下忍或從中忍起增上忍世間第一，入於見道乃至究竟阿羅漢果，此人或時於第三生得入聖已於初果身命終受生受於七有方便般涅槃。

Regarding the third [section], explaining the limits of cultivation as slow or swift, there are three types in all: First, those of the utmost duration: a śrāvaka, at the very most, undergoes sixty kalpas cultivating the roots of goodness conducive to liberation and achieves parinirvāṇa in their final body. Second, those not of the utmost duration: there are some who undergo multiple lifetimes up to one kalpa, and only then achieve parinirvāṇa. Third, those who achieve parinirvāṇa most swiftly must undergo three lifetimes. In the first lifetime, they arouse the mind to cultivate the goodness conducive to liberation, namely the contemplation of the fivefold stilling of the mind and the general and specific applications of mindfulness. In the second lifetime, they again cultivate the applications of mindfulness, proceeding from the general applications of mindfulness to cultivate toward heat and summits, or enter the lower [degree of] acceptance, or enter the middle [degree of] acceptance, which is called achievement. In the third lifetime, again from the lower acceptance or from the middle acceptance, they arouse the supreme acceptance and worldly supreme dharmas, enter the path of seeing, up to the ultimate fruition of arhatship. Or, this person, having attained entry into the noble [path] in the third lifetime, passes away in the body of the first fruition, takes rebirth, undergoes seven existences, and expediently achieves parinirvāṇa.
