Tithi-Nirṇaya for Vratas: Ekādaśī Rules, Saṅkrānti Punya-kāla, Eclipse Observances, and Prāyaścitta
मुहूर्तद्वितयं ग्राह्यं भगवत्युदिते रवौ । प्रदोषव्यापिनी ग्राह्या तिथिर्नक्तव्रते सदा ॥ ९ ॥
muhūrtadvitayaṃ grāhyaṃ bhagavatyudite ravau | pradoṣavyāpinī grāhyā tithirnaktavrate sadā || 9 ||
Cuando ha salido el Sol divino, deben tomarse dos muhūrtas como el período apropiado. Y para el voto nocturno (naktavrata), ha de aceptarse siempre la tithi que se extiende hasta pradoṣa, el crepúsculo del anochecer.

Vrata: naktavrata
Primary Rasa: shanta
Secondary Rasa: bhakti
It teaches that dharma is protected by correct observance of time—choosing the proper muhūrta and the tithi that truly ‘connects’ with pradoṣa ensures the vow is performed in its intended sacred window.
Bhakti is expressed through disciplined worship; by observing vows at the correct ritual times (sunrise measures and pradoṣa-linked tithi), the devotee offers worship with attentiveness and scriptural fidelity.
Vedāṅga-oriented timekeeping—especially kalā/muhūrta measurement and tithi-vyāpti (tithi’s extension into pradoṣa), a core principle used in ritual calendars and traditional jyotiṣa-based vrata decisions.
