First, not explaining the ten divisions of time: the Abhidharmakośabhāṣya states: 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; thirty days and nights make one month; twelve months make one year; one year makes three seasons, namely cold, heat, and rain, each having four months; there are only eight levels. Here, differing from that, it establishes ten times: a half-month is fifteen days; fifteen days of muhūrtas constitute night; fifteen days of muhūrtas constitute day; "time" refers to kalpas beyond the year, as previously explained.
