It frames sacred time (kāla) as a dharmic structure: months and fortnights are not merely astronomical, but are linked to Deva- and Pitṛ-oriented duties, guiding a practitioner to align worship and ancestral rites with the lunar rhythm.
By distinguishing the bright and dark fortnights as ‘divine’ and ‘ancestral,’ it supports bhakti as disciplined, time-aligned practice—choosing appropriate lunar periods for Vishnu worship, vows (vrata), and offerings, so devotion becomes steady and ritually coherent.
Vedāṅga Jyotiṣa (Vedic calendrics/astronomy): the verse summarizes how lunar months and pūrṇimā are named and how pakṣas (śukla/kṛṣṇa) are classified for different ritual purposes, especially Deva-kārya and Pitṛ-kārya (e.g., śrāddha).
