The Account of Mohinī (Mohinī-kathanam): Ekādaśī Nirṇaya, Daśamī Boundary, and Aruṇodaya
त्रयोदशान्मुहूर्तांत्तु रात्रैरूर्द्ध्वा समागता । सब्ध्वोपवासिनां पुण्यं स्वस्था भव शुचिस्मिते ॥ १५ ॥
trayodaśānmuhūrtāṃttu rātrairūrddhvā samāgatā | sabdhvopavāsināṃ puṇyaṃ svasthā bhava śucismite || 15 ||
After thirteen muhūrtas of the night have passed, the proper time arrives. Then the merit gained by those who observe the fast (upavāsa) is fulfilled—be well and at ease, O you of pure smile.

It links spiritual merit (puṇya) to disciplined observance of time (kāla): the fast bears full fruit when concluded/observed at the proper night-muhūrta, showing that dharma is strengthened by precision and restraint.
By emphasizing faithful adherence to a vrata’s timing, it portrays devotion as steady, rule-guided worship—bhakti expressed through self-control (upavāsa) and reverence for śāstric injunctions.
It highlights kāla-vicāra (time-reckoning) using the muhūrta unit—knowledge aligned with Jyotiṣa/Vedāṅga-style calendrical timing used to correctly perform vows and ritual observances.
