次就行論。如《地持》說，種性解行修習小行，有斷行不定、所得有退。起行局狹故名為小，不能常行說為有斷，行心不堅故名不定，逢緣退失名有退轉。歡喜乃至緣起慧住，修習廣行，不斷決定、所得不退。此諸住中，各於一行備一切行故名為廣，恒作不住名為不斷，行心牢固稱曰決定，緣不能敗名不退轉。有行有開，乃至最上修無量行，不斷決定、所得不退。此諸住中，各能於彼一切行中備具一切，名無量行。餘不斷等，備如前釋。彼如來住，成就無量不斷決定不退之果（此四門竟）。

Next, discussing according to practice: As taught in the Bodhisattvabhūmi, in the lineages and resolve-conduct one cultivates minor practice, which has interruptions, is indeterminate, and what is attained admits of retrogression. Because the arising of practice is narrow, it is called minor; being unable to practice constantly, it is described as having interruptions; because the mind of practice is not firm, it is called indeterminate; and encountering conditions and losing it, it is said to admit of retrogression. From joy up to the wisdom of dependent origination, one cultivates vast practice, which is uninterrupted, determinate, and what is attained does not retrogress. In each of these abodes, one practice is equipped with all practices, hence it is called vast; acting constantly without ceasing, it is called uninterrupted; the mind of practice being firm, it is termed determinate; and conditions being unable to destroy it, it is named non-retrogression. From having activity and development up to the supreme [abode], one cultivates immeasurable practice, which is uninterrupted, determinate, and what is attained does not retrogress. In these abodes, one is able in all practices to possess everything completely, hence they are called immeasurable practice. The rest, such as uninterrupted, are fully as explained before. That Tathāgata abode accomplishes the immeasurable, uninterrupted, determinate, and non-retrogressing fruit. (This concludes the fourth portal.)
