第三約就縛脫辨異。若是解脫不繫相者，是其數滅；有是解脫，非不繫相，是非數滅。未來染過，永更不生，通名解脫。有非解脫、非不繫相，是無常滅。此言不盡。理實無常通脫非脫。無漏無常是其解脫，有漏無常是非解脫。繫與不繫，類亦同爾。

Third, distinguishing differences in terms of bondage and liberation. If it is liberation and bears the characteristic of being unattached, that is cessation through deliberation. That which is liberation but does not bear the characteristic of being unattached is cessation not through deliberation: future defiled faults never arising again is generically named liberation. That which is neither liberation nor of the characteristic of being unattached is impermanent cessation. This statement is not exhaustive: in actual truth, impermanence covers both liberation and non-liberation. Untainted impermanence is liberation; tainted impermanence is non-liberation. Bondage and non-bondage are categorized in the same way.
