പ്രിയ പുത്രകാ! മുനികളും വേദവ്യാസനും പ്രസ്താവിച്ച ഏത് ഫലമോ, ശുക്ലപക്ഷമായാലും കൃഷ്ണപക്ഷമായാലും—വിഷ്ണുവിനായി ജാഗരണം ചെയ്താൽ അതേ ഫലം ലഭിക്കുന്നു.
Unspecified (contextually a narrator/teacher within Dvārakā Māhātmya)
Tirtha: Dvārakā
Type: kshetra
Listener: pūtraka (dear child)
Scene: A teacher addresses a ‘child’ (pūtraka) and declares that the sages’ and Vyāsa’s promised reward is attained by keeping vigil for Viṣṇu in either fortnight; night setting with lamps and devotional singing implied.
Keeping a devotional night vigil for Viṣṇu is equated with the highest merits praised by the sages.
The broader context is Dvārakā Māhātmya, celebrating Dvārakā and Vaiṣṇava observances connected with it.
Viṣṇu-jāgara—staying awake in devotional vigil—applicable in both śukla and kṛṣṇa pakṣa.
