तदोपवासः कर्तव्यो भूतायां सद्भिरादरात् । कृतनित्यक्रियः सोम त्रयोदश्यां निशामय
tadopavāsaḥ kartavyo bhūtāyāṃ sadbhirādarāt | kṛtanityakriyaḥ soma trayodaśyāṃ niśāmaya
Entonces, en esa ocasión, los justos deben ayunar con reverencia en la (precedente) tithi llamada Bhūtā. Cumplidos los ritos diarios obligatorios, oh Soma, vela en la decimotercera luna.
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.
