Narada (teaching in a vrata/ritual context within the Narada Purana dialogue tradition)
Vrata: Dvādaśī-Viṣṇu-vrata (Jalaśāyī worship on Dvādaśī)
Primary Rasa: bhakti
Secondary Rasa: shanta
It teaches that faith-filled fasting (upavāsa) culminates in proper worship (arcana) of Viṣṇu, making a lunar observance (Dvādaśī in Mārgaśīrṣa śukla-pakṣa) a direct means to cultivate devotion and merit through disciplined ritual.
Bhakti is framed as sincere, regulated worship: the devotee fasts, then worships Viṣṇu “properly” and “with śraddhā,” emphasizing inner faith expressed through outward devotional practice.
It relies on Vedāṅga-style calendrical discipline: identifying the correct lunar timing (śukla-pakṣa, Dvādaśī, month of Mārgaśīrṣa) for a vrata, reflecting Jyotiṣa-based ritual scheduling used in Purāṇic observances.
