So, instructing His sons. It is the duty of the father that before retirement . . . now, here is one significant point. Why the king was retiring? That is the system, Vedic system. Either one is king or one is ordinary human being, at a certain age he must retire. That is Vedic system. Not that because one is king and one has ample opportunity for sense enjoyment, therefore he should indulge in sense enjoyment without retiring from family life. That is not Vedic system. The Vedic system is, the aim is, how to elevate oneself to the perfection of Kṛṣṇa consciousness. That is Vedic system.
You have read Bhagavad-gītā. In the Fifteenth Chapter, fifteenth verse, you'll find, vedaiś ca sarvair aham eva vedyam (BG 15.15). The whole Vedic system is designed, or planned, how to know Kṛṣṇa. So if you follow Vedic system, then the ultimate objective should be to know Kṛṣṇa. That is the Vedic version and corroborated by Lord Kṛṣṇa Himself. He is the original compiler of Vedas; therefore His version should be accepted, that the objective of studying Vedas means to know Kṛṣṇa. That's all. Vedaiś ca sarvair aham eva vedyaḥ.
Therefore the king, Ṛṣabhadeva, is advising, instructing His sons . . . He was retiring. Why He was retiring? He could enjoy His kingdom. Just like at the present moment, either a king or a family man does not retire. Even a poor man living in with family with great difficulties, but if you ask him to retire, he'll not be agreeable. We have asked many old men—he's suffering, he's not happy within his family members—but if I say: "Why you are taking so much trouble with the family? Why not come and live with us in Kṛṣṇa consciousness Society?" he'll not agree. Because he has no Vedic training. Up to the end of this life he'll stick to the family life.
