Once while touring the world, Lord Ṛṣabhadeva, the Supreme Lord, reached a place known as Brahmāvarta. There was a great conference of learned brāhmaṇas at that place, and all the King’s sons attentively heard the instructions of the brāhmaṇas there. At that assembly, within the hearing of the citizens, Ṛṣabhadeva instructed His sons, although they were already very well-behaved, devoted and qualified. He instructed them so that in the future they could rule the world very perfectly. Thus he spoke as follows.
