Kāla-vibhāga: The Divisions of Time from Atom to Brahmā, and the Lord Beyond Time
लघूनि वै समाम्नाता दश पञ्च च नाडिका । ते द्वे मुहूर्त: प्रहर: षड्याम: सप्त नृणाम् ॥ ८ ॥
laghūni vai samāmnātā daśa pañca ca nāḍikā te dve muhūrtaḥ praharaḥ ṣaḍ yāmaḥ sapta vā nṛṇām
十五拉古为一那底迦(檀荼)。两檀荼为一牟呼尔多;按人间算法,六或七檀荼为一更(夜分,yāma)。
This verse defines a sequence of human time units—15 laghus = 1 nāḍikā, 2 nāḍikās = 1 muhūrta, and 2 muhūrtas = 1 prahara—building up to the day and week.
In Canto 3 Chapter 11, Śukadeva explains how time is measured from subtle to gross scales to show time’s role as the Lord’s regulating potency within creation.
By seeing time as sacred and structured, one can plan sādhana (japa, study, worship) in disciplined cycles (like muhūrtas), reducing distraction and increasing remembrance of the Lord.
