俱舍論記 12.8

12.8

「眾緣和合至一剎那量」者，現緣和合法得自體頃，即便落謝更不經停，名一剎那。或有動法，行度一極微，名一剎那。諸法實無行動，相續道中假說動故。對法師說，如文可知。廣釋剎那量，如《婆沙》一百三十六。

"When the assembly of conditions coalesces... up to: the measure of one kṣaṇa": When a conditioned dharma obtains its intrinsic nature during the coalescence of present conditions, it immediately perishes and does not endure any longer; this is called one kṣaṇa. Or, for a moving dharma, traversing one paramāṇu is called one kṣaṇa. Real dharmas have no motion; motion is only metaphorically posited within the course of continuity (saṃtati). The explanation of the Ābhidharmikas can be known from the text. A detailed explanation of the measure of a kṣaṇa is found in fascicle 136 of the Mahāvibhāṣā.
