Synonyms
trasareṇu-trikam—combination of three hexatoms;bhuṅkte—as they take time to integrate;yaḥ—that which;kālaḥ—duration of time;saḥ—that;truṭiḥ—by the nametruṭi;smṛtaḥ—is called;śata-bhāgaḥ—one hundredtruṭis;tu—but;vedhaḥ—called avedha;syāt—it so happens;taiḥ—by them;tribhiḥ—three times;tu—but;lavaḥ—lava;smṛtaḥ—so called.
Translation
The time duration needed for the integration of three trasareṇus is called a truṭi, and one hundred truṭis make one vedha. Three vedhas make one lava.
Purport
It is calculated that if a second is divided into 1, 687.5 parts, each part is the duration of a truṭi, which is the time occupied in the integration of eighteen atomic particles. Such a combination of atoms into different bodies creates the calculation of material time. The sun is the central point for calculating all different durations.
