Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sukadeva Gosvami said: Thus the great well-wisher of everyone, the Supreme Lord Rsabhadeva, instructed His own sons. Although they were perfectly educated and cultured, He instructed them just to set an example of how a father should instruct his sons before retiring from family life. Sannyasis, who are no longer bound by fruitive activity and who have taken to devotional service after all their material desires have been vanquished, also learn by these instructions. Lord Rsabhadeva instructed His one hundred sons, of whom the eldest, Bharata, was a very advanced devotee and a follower of Vaisnavas. In order to rule the whole world, the Lord enthroned His eldest son on the royal seat. Thereafter, although still at home, Lord Rsabhadeva lived like a madman, naked and with disheveled hair. Then the Lord took the sacrificial fire within Himself, and He left Brahmavarta to tour the whole world.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Actually the instructions given to Lord Rsabhadeva’s sons were not exactly meant for His sons because they were already educated and highly advanced in knowledge. Rather, these instructions were meant for sannyasis who intend to become advanced devotees. Sannyasis must abide by Lord Rsabhadeva’s instructions while on the path of devotional service. Lord Rsabhadeva retired from family life and lived like a naked madman even while still with His family.
