शरणागतानां परिपालनेन ह्यन्नप्रदानेन शृणुष्व पुत्र । ऋणप्रदाने द्विजदेवतानां तद्वै फलं जागरणेन् विष्णोः
śaraṇāgatānāṃ paripālanena hyannapradānena śṛṇuṣva putra | ṛṇapradāne dvijadevatānāṃ tadvai phalaṃ jāgaraṇen viṣṇoḥ
孩子啊，且听：护持来投靠者、施与饮食、并偿还对“二生如神”的婆罗门（dvija-devatā）所欠之债——由此所得之功德，同样确实可由为毗湿奴守持圣夜不眠（jāgara，达瓦拉迦中）而获得。
Skanda (deduced from Dvārakā Māhātmya didactic narration style within Skanda Purāṇa)
Tirtha: Dvārakā-jāgaraṇa (Viṣṇu)
Type: kshetra
Listener: Putra (disciple/son figure)

FAQs

Dvārakā is glorified through the Dvārakā Māhātmya context, presenting it as a powerful setting for Viṣṇu worship and jāgaraṇa.
Viṣṇu-jāgaraṇa—staying awake in devotional observance (night vigil) for Viṣṇu—is prescribed as a high-merit practice, comparable to annadāna, śaraṇāgata-protection, and repaying dues to brāhmaṇas.
