Maṅgalācaraṇa, Naimiṣāraṇya-Sabhā, Sūta-Āhvāna, and Narada Purāṇa-Māhātmya
कथं हरौ मनुष्याणां भक्तिरव्यभिचारिणी । केन सिध्येत च फलं कर्मणस्त्रिविधात्मनः ॥ १३ ॥
kathaṃ harau manuṣyāṇāṃ bhaktiravyabhicāriṇī | kena sidhyeta ca phalaṃ karmaṇastrividhātmanaḥ || 13 ||
How does unwavering, undeviating bhakti to Hari (Vishnu) arise in human beings? And by what means is the fruit of karma—of threefold nature—brought to fulfillment?
Narada
Vrata: none
Primary Rasa: bhakti
Secondary Rasa: jijnasa
It frames the core inquiry of the text’s teaching: how humans can cultivate exclusive devotion to Hari and how such devotion relates to the maturation (siddhi) of karmic results, pointing toward dharma aligned with liberation.
By asking specifically for “avyabhicāriṇī bhakti” (unwavering devotion), the verse highlights bhakti as a disciplined, single-point orientation to Hari rather than a mixed or wavering practice, setting up instruction on stable devotional life.
No specific Vedanga (like Vyākaraṇa, Jyotiṣa, or Kalpa) is named; the verse is a doctrinal question about karma and its threefold classification, which later connects to practical dharma and ritual conduct (kalpa) in a broader sense.
