八、重三等持，雖無文說，理亦通有。然非唯無學不時解脫起，異生有學亦能起故，不唯有漏，亦通無漏故。《顯揚》第四說道諦四行通三解脫門，即三等持重緣之行是無漏故，如理應知。今此論文自列三別相，及釋前後妨難不同，并前合以十門分別。

Eighth, as for the repeating of the three samādhis: although not explicitly mentioned in the text, logically they are also admitted to exist. However, they are not generated solely by the non-learners (aśaikṣa) who are liberated at all times, because ordinary beings and learners (śaikṣa) can also generate them; nor are they only tainted, because they also extend to the untainted. Fascicle four of the Prakaraṇāryavācā states that the four aspects of the truth of the path extend to the three doors of liberation, meaning that the practices of the three samādhis taking [the preceding ones] as objects again are untainted, as should be understood in accordance with reason. Now, this root text itself lists their three distinct characteristics, and resolves the differences in difficulties and objections earlier and later; combined with what precedes, they are analyzed across ten headings.
