Matsya Purana — Indra Sends Soma to Battle: Frost-Weapon
क्षयवृद्धी तव व्यक्ते सागरस्येव मण्डले परिवर्तस्यहोरात्रं कालं जगति योजयन् //
kṣayavṛddhī tava vyakte sāgarasyeva maṇḍale parivartasyahorātraṃ kālaṃ jagati yojayan //
Your manifest waxing and waning—like the ocean’s circular expanse—sets the turning of day and night in motion, thereby measuring and applying Time within the world.
It presents Kāla (Time) as a divine, world-governing force expressed through recurring cycles (day and night), the same cyclic logic that also underlies larger rhythms like dissolution and renewal.
By grounding order in regular cycles, it implies that rulers and householders should align conduct, vows, and governance with disciplined timekeeping—daily duties (nitya-karma) and timely decision-making reflect cosmic order.
Indirectly, it supports ritual scheduling: rites, temple services, and observances depend on ahorātra (day–night reckoning), a foundational principle for calendrical timing used in worship and consecrations.
