二、出體者，《對法》、《顯揚》俱作是說：初二勝處，初解脫所出；次二勝處，是第二解脫所出；後四勝處，第三解脫所出。淨解脫中，初之二想淨與不淨，展轉相待，展轉相入。如是展轉，總一切色合為一味清淨想解，名展轉一味故。後四勝處，第三解脫所出。故此八體即前三解脫也。

Second, concerning the emergence of their essential nature: Both the Abhidharmasamuccaya and the Prakaraṇāryavācā state: The first two abhibhvāyatanas arise from the first vimokṣa; the next two abhibhvāyatanas arise from the second vimokṣa; the last four abhibhvāyatanas arise from the third vimokṣa. Within the pure vimokṣa, the initial two saṃjñās of the pure and the impure mutually contrast with and mutually penetrate one another. In this manner of mutual [penetration], universally combining all forms into a resolute concept of a single taste of purity is called "mutual single taste." Therefore, the last four abhibhvāyatanas arise from the third vimokṣa. Hence, the essential nature of these eight is precisely the previous three vimokṣas.
