तदोपवासः कर्तव्यो भूतायां सद्भिरादरात् । कृतनित्यक्रियः सोम त्रयोदश्यां निशामय
tadopavāsaḥ kartavyo bhūtāyāṃ sadbhirādarāt | kṛtanityakriyaḥ soma trayodaśyāṃ niśāmaya
Alors, en cette occasion, les justes doivent jeûner avec révérence au (précédent) tithi nommé Bhūtā. Après avoir accompli les rites quotidiens obligatoires, ô Soma, veille durant le treizième jour lunaire.
Śiva (Maheśāna)
Tirtha: Candreśvara (Kāśī)
Type: kshetra
Listener: Soma (Candra)
Scene: Devotees in Kāśī preparing for vrata: morning sandhyā by lamp, then a simple fasting meal withheld; at night, a vigil with rows of oil lamps, quiet chanting, and steady attention toward the shrine.
Discipline in time—fasting, completing nitya-karmas, and keeping vigil—purifies devotion and strengthens vrata-power.
The vrata is taught in the Candreśvara/Kāśī context, implying observance in Kāśī for heightened merit.
Upavāsa (fasting), performance of nitya-kriyā, and niśā-jāgaraṇa (night vigil) on trayodaśī in relation to Somavāra-Amāvāsyā.
