仁王經疏 3.278

3.278

釋曰：第二、釋其行相。知三世法者，標三明。知三世法無來無去無住處者，別顯三明所行之境，謂未來未有、過去已滅、現在不住，不同薩婆多宗三世皆有實體。心心寂滅者，所緣無故，能緣之心念念寂滅。

Explanation: Second, explaining its active characteristics. 'Knowing the dharmas of the three times' marks the three clarities. 'Knowing that the dharmas of the three times have neither coming nor going, nor an abode' specifically shows the realm in which the three clarities operate, meaning that the future does not yet exist, the past has already ceased, and the present does not abide, unlike the Sarvāstivāda school's assertion that the three times all possess real substance. 'Each and every thought-moment is tranquil and ceased' means that because the objective support is absent, the cognitive mind in every thought-moment is tranquil and ceased.
