SB 1.8.45, Translation and Purport:

Thus accepting the prayers of Śrīmatī Kuntīdevī, the Lord subsequently informed other ladies of His departure by entering the palace of Hastināpura. But upon preparing to leave, He was stopped by King Yudhiṣṭhira, who implored Him lovingly.

No one could make Lord Kṛṣṇa stay at Hastināpura when He decided to start for Dvārakā, but the simple request of King Yudhiṣṭhira that the Lord remain there for a few days more was immediately effective. This signifies that the power of King Yudhiṣṭhira was loving affection, which the Lord could not deny. The almighty God is thus conquered only by loving service and nothing else. He is fully independent in all His dealings, but He voluntarily accepts obligations by the loving affection of His pure devotees.
