起信論疏筆削記 20.6

20.6

苦觀中，論　一切心行等，如經中說：一念有九十剎那，一剎那中九百生滅，既速生速滅，誠為苦也。故前云：動則有苦，果不離因。然苦者，逼迫為義，五苦、八苦種種不同，略而論之不離三種，謂苦苦、壞苦、行苦。三苦之內行苦最通，不唯五趣皆有，抑亦三乘悉具。今就通義，故標一也。

Under the contemplation of suffering, the Śāstra says: "All mental activities, etc.": as stated in the sūtras, in a single thought-moment there are ninety kṣaṇas, and within one kṣaṇa there are nine hundred arisings and ceasings. Since they arise rapidly and cease rapidly, this is truly suffering. Therefore it was said earlier: "If there is movement, there is suffering; the fruit is not separate from the cause." Now, "suffering" has the meaning of affliction; the five sufferings and eight sufferings are manifold and varied, but speaking in brief they do not go beyond three kinds, namely the suffering of suffering, the suffering of change, and the suffering of conditioned existence. Among the three sufferings, the suffering of conditioned existence is the most universal; not only do the five destinies all have it, but the three vehicles also all possess it. Now, taking the universal meaning, only one is indicated.
