剎那（上音察梵語時名也俱舍論頌曰　百二十剎那　為怛剎那量臘縛此六十　此三十須臾　共成一晝夜　謹案此頌一日一夜有三十須臾。每一須臾計有三十臘縛。又於一臘縛之中計有六十怛剎那。又於一怛剎那之中分為一百二十剎那。時中迅促不過剎那。今依此國曆法凡一日一夜有十二時共分為一百刻每時分得八刻少強約其大數均分從寅至丣一時之中計有五十四萬剎那。餘時准此計一日一夜總六百四十八萬剎那。若以每刻分之即一刻之中約有七萬剎那時也言極迅疾促於瞬息也）。

剎那 (kṣaṇa: the first character has the pronunciation 察. A Sanskrit name for time. A verse in the Abhidharmakośa-bhāṣya says: / 'One hundred and twenty kṣaṇas / make the measure of one tatkṣaṇa; / sixty of these make a lava, / and thirty of these a muhūrta, / which together make one day and night.' / I respectfully examine that, according to this verse, one day and night has thirty muhūrtas (須臾). Each single muhūrta is calculated as having thirty lavas (臘縛). Moreover, within one lava there are calculated to be sixty tatkṣaṇas (怛剎那). And within one tatkṣaṇa, it is divided into one hundred and twenty kṣaṇas (剎那). Among divisions of time, there is nothing swifter or shorter than a kṣaṇa. Now, relying on the calendrical methods of this land [China], a single day and night has twelve double-hours, collectively divided into one hundred ke (刻). Each double-hour gets eight ke and slightly more. Averaging their approximate number equally, within a single double-hour from yín to mǎo, there are calculated to be 540,000 kṣaṇas. The other double-hours follow this standard, calculating a total of 6,480,000 kṣaṇas for a day and night. If one divides it by each ke, then within a single ke there is approximately the time of 70,000 kṣaṇas. This expresses what is extremely swift and brief, shorter than the blink of an eye.)
