Narada
Vrata: Dvadashi-vrata (fasting on Dvādaśī; likely within a Viṣṇu-vrata sequence)
Primary Rasa: bhakti
Secondary Rasa: shanta
It elevates a simple, accessible vrata—fasting on Caitra-śukla Dvādaśī—by declaring it yields the full merit of a major Vedic sacrifice, showing that disciplined observance can substitute for costly rituals.
By valuing fasting on an auspicious tithi (commonly associated with Vaiṣṇava observances), the verse frames bodily restraint and sacred-time discipline as supportive practices that deepen devotion and purity of mind.
It relies on calendrical precision—month (Caitra), fortnight (śukla pakṣa), and tithi (Dvādaśī)—reflecting practical Jyotiṣa-style timekeeping used to schedule vrata and ritual observances.
