Dvādaśī-vrata: Month-by-month Viṣṇu Worship and the Year-End Udyāpana
नांमभिः केशवाद्यैश्च ह्युपचाराप्रकल्पयेत् । रात्रौ जागरणं कुर्यात्पुराणश्रवणादिभिः ॥ ९८ ॥
nāṃmabhiḥ keśavādyaiśca hyupacārāprakalpayet | rātrau jāgaraṇaṃ kuryātpurāṇaśravaṇādibhiḥ || 98 ||
Dengan nama-nama suci seperti Keśava dan lainnya, hendaknya menyusun upacara pemujaan bagi Tuhan. Pada malam hari hendaknya berjaga melalui mendengarkan Purāṇa dan laku bhakti sejenisnya.
Sanatkumara (in instruction to Narada, within the Narada–Sanatkumara dialogue)
Vrata: none
Primary Rasa: bhakti
Secondary Rasa: shanta
It teaches that devotion is strengthened through nāma (invoking Vishnu’s sacred names) and disciplined worship, culminating in a night-vigil sustained by sacred listening, which keeps the mind absorbed in dharma and remembrance.
Bhakti is shown as practical: serve the Lord with upacāras while chanting/reciting His names (like Keśava), and deepen devotion through jāgaraṇa supported by Purāṇa-śravaṇa—continuous hearing and contemplation of divine deeds and teachings.
The emphasis is ritual procedure (upacāra-vidhi) and disciplined observance (vrata-style jāgaraṇa); while not a technical Vedāṅga lesson, it aligns with correct liturgical practice and recitation-based worship.
