第三、淨背捨位在三禪中，故論云：「淨背捨者，緣淨故淨，遍身受樂，故名身作證。」三界之法，若除三禪，更無遍身之樂。論文又言：「是四禪中有一背一捨、四勝處。」如比上進退從容，當知位在三禪、四禪，苟而遍屬，即互乖論。今若具以此義破射於前，及融通教意，甚自紜紜。下五背捨配位不異於前，今依後家之釋，以辯位次也。

Third, the pure liberation has its station in the third dhyāna; hence the treatise states: 'As for the pure liberation, because it conditions purity it is pure, and one experiences pleasure throughout the entire body, so it is called personally realizing it.' Among the phenomena of the three realms, apart from the third dhyāna, there is no other pleasure throughout the entire body. The treatise also states: 'In the fourth dhyāna, there is one turning away and one relinquishing, and four stations of mastery.' Following this orderly advance and retreat, one should know that its station lies in the third and fourth dhyānas; if one blindly assigns it to everything, it would contradict the treatise. If we were now to thoroughly use this meaning to refute the previous views and harmonize the teaching's import, it would become exceedingly convoluted. The lower five liberations are assigned to stations no different from the former. We now rely on the latter master's explanation to distinguish the order of stations.
