A measure of time defined as consisting of two blinks of the eye. Eight lavas make one kāṣṭhā, which means that the duration of one lava is three hundred seventy-five milliseconds. Term lava is thus commonly used to refer to a brief moment in time. According to another time system, lava refers to a thirtieth part of a muhūrta, giving it a duration of one minute and thirty-six seconds. This is also how Vasubandhu defines lava in the Abhidharmakośa (III 88): thirty lavas make one muhūrta, and thirty muhūrtas make one full day and night.
