Sanskrit:
सूत उवाचसम्प्रस्थिते द्वारकायां जिष्णौ बन्धुदिदृक्षया ।ज्ञातुं च पुण्यश्लोकस्य कृष्णस्य च विचेष्टितम् ॥ १ ॥
ITRANS:
sūta uvācasamprasthite dvārakāyāṁjiṣṇau bandhu-didṛkṣayājñātuṁ ca puṇya-ślokasyakṛṣṇasya ca viceṣṭitam
Translation:
Śrī Sūta Gosvāmī said: Arjuna went to Dvārakā to see Lord Śrī Kṛṣṇa and other friends and also to learn from the Lord of His next activities.
Purport:
As stated in Bhagavad-gītā, the Lord descended to the earth for the protection of the faithful and annihilation of the impious, so after the Battle of Kurukṣetra and establishment of Mahārāja Yudhiṣṭhira, the mission of the Lord was complete. The Pāṇḍavas, especially Śrī Arjuna, were eternal companions of the Lord, and therefore Arjuna went to Dvārakā to hear from the Lord of His next program of work.
