須臾（玉篇曰須臾俄頃也按俱舍論本行集等云時中最少名一剎那一百二十剎那名一怛剎那六十怛剎那名一羅婆三十羅婆名一牟呼栗多三十牟呼栗多名一晝夜准大集經一日一夜有三十須臾即牟呼栗多是也經云從日出看人影長九十六尺為第一須臾云云也）。

須臾 (an instant [muhūrta]: the Yupian says: "Xuyu is a brief moment." According to the Abhidharmakośa-bhāṣya, the Abhiniṣkramaṇa-sūtra, and others: the smallest division of time is called one kṣaṇa; one hundred and twenty kṣaṇas make one tatkṣaṇa; sixty tatkṣaṇas make one lava; thirty lavas make one muhūrta; thirty muhūrtas make one day and night. Based on the Mahāsaṃnipāta-sūtra, one day and night consists of thirty xuyu, which are precisely muhūrtas. The sūtra says that looking at a person's shadow from sunrise when it is ninety-six feet long is the first xuyu, and so forth).
