大乘義章 2.53

2.53

第二約得解脫辨異。若法滅已得解脫得，是其數滅；若法滅已，而不得於解脫之得，是非數滅。若法散壞，亦不得於解脫之得，是無常滅。

Second, distinguishing differences in terms of the attainment of liberation. If a dharma has ceased and the attainment of liberation is obtained, that is cessation through deliberation. If a dharma has ceased and the attainment of liberation is not obtained, that is cessation not through deliberation. If a dharma disintegrates and disappears and the attainment of liberation is likewise not obtained, that is impermanent cessation.
