“The shortest portion of time is called a t’sa-na (kshana); 120 kshanas make a ta-t’sa-na (takshana); 60 of these make a la-fo (lava); 30 of these make a mau-hu-li-to (muthurta); five of these make “a period of time” (kala); six of these make a day and night (ahoratra), but commonly the day and night are divided into eight kalas. 316”
