Calculation of Time, from the Atom
413
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 1687.5 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.

निमेषस्त्रित्त्रो ज्ञेय आम्नातस्ते त्रयः क्षणः । क्षणान् पञ्च विदुः काष्ठां लघु ता दश पञ्च च ॥ ७ ॥
nimeṣas tri-lavo jñeya āmnātas te trayaḥ kṣaṇaḥ kṣaṇān pañca viduḥ kāṣṭhām laghu tā daśa pañca ca
nimeṣaḥ—duration of time called a nimeṣa; tri-lavaḥ—duration of three lavas; jñeyaḥ—is to be known; āmnātaḥ—it is so called; te—they; trayaḥ—three; kṣaṇaḥ—duration of time called a kṣaṇa; kṣaṇān—such kṣaṇas; pañca—five; viduḥ—one should understand; kāṣṭhām—duration of time called a kāṣṭhā; laghu—duration of time called a laghu; tāḥ—those; daśa pañca—fifteen; ca—also.
TRANSLATION
The duration of time of three lavas is equal to one nimeṣa, the combination of three nimeṣas makes one kṣaṇa, five kṣaṇas combined together make one kāṣṭhā, and fifteen kāṣṭhās make one laghu.
PURPORT
By calculation it is found that one  laghu  is equal to two minutes. The atomic calculation of time in terms of Vedic wisdom may be converted into present time with this understanding.
