trasareṇu-trikaṁ bhuṅkte
yaḥ kālaḥ sa truṭiḥ smṛtaḥ
śata-bhāgas tu vedhaḥ syāt
tais tribhis tu lavaḥ smṛtaḥ
The time it takes for the sun to pass over three trasareṇus is called a truṭi. A hundred truṭis make one vedha. Three vedhas make one lava.
Three trasareṇus make one truṭi. According to Surya-siddhānta, a truṭi is defined as the time taken for a needle to pierce a lotus leaf. One hundred truṭis make a vedha. Three vedhas make a lava.

nimeṣas tri-lavo jñeya
āmnātas te trayaḥ kṣaṇaḥ
kṣaṇān pañca viduḥ kāṣṭhāṁ
laghu tā daśa pañca ca
Three lavas make one nimeṣa. Three nimeṣas make one kṣaṇa. Fire kṣaṇas make one kāṣṭhā. Fifteen kāṣṭhās make one laghu.
Āmāntāḥ means “is called.” Tāh means kāsṭhāḥ.

laghūni vai samāmnātā
daśa pañca ca nāḍikā
te dve muhūrtaḥ praharaḥ
ṣaḍ yāmaḥ sapta vā nṛṇām
Fifteen laghus make one nādīkā. Two nāḍikās make one muhūrta. Six or seven nāḍikās make a prahara or yāma for humans.
Six or seven nāḍikās make a prahara or yāma. Day and night are divided into four parts. When the day or night is short then there are six nāḍikas in a prahara. When the day or night is long then there are seven nāḍikas in a prahara. This does not include the nāḍikā at the two sandhyas. Because it is impossible to list all the differences for each day of the year, the time is not fixed. This indicated by the word vā.
|| 3.11.9 ||
dvādaśārdha-palonmānaṁ
caturbhiś catur-aṅgulaiḥ
svarṇa-māṣaiḥ kṛta-cchidraṁ
yāvat prastha-jala-plutam
The measuring pot for one nāḍikā, or daṇḍa, can be prepared with a six-pala-weight [fourteen ounce] pot of copper, in which a hole is bored with a gold probe weighing four māṣa and measuring four fingers long. When the pot is placed on water, the time before the water overflows in the pot is called one daṇḍa or nāḍikā.
This verse defines the length of the nāḍikā. Unmānam means that by which something is measured. Here it refers to a copper pot weight of six palas. Sixty-four māśas make one pala. One should make a hole in the pot using a gold needle four fingers in length and weighting four māṣas. Five guñjas make one māṣa. The time it takes forl one prastha of water to enter the vessel and fill it is a nāḍikā. If the weight of the vessel is more or the hole is larger, the pot will sink more quickly. If the vessel is lighter and the hole smaller, the pot will sink more slowly. Thus the exact weight of the pot and the size of the hole are specified. If the needle is made of silver and the same length and weight, the hole will be bigger.
