In plain words
Kaṃsa had two wives. Their father marched against Kṛṣṇa. The people of Vrepalle went to Kṛṣṇa: “How many days must we go on suffering these hardships?” they lamented. Then Kṛṣṇa: “Do not be afraid. Understand My power and might. Tonight, if all of you lie down to sleep in this Vrepalle, see where you are by daybreak,” He said. Those who lay down that night in Vrepalle rose at dawn to find themselves in Dvārakā! Where is Vrepalle, and where is Dvārakā! The distance between them is a thousand miles. In this way Kṛṣṇa went on working many wonders. God can do anything. So do not give room to doubts. Doubts alone are drowning you. Follow Divinity with deep and complete faith.
