The Great Epic of the Bhārata dynasty 1.80.21

1.80.21

śukreṇa ca varo dattaḥ kāvyenośanasā svayam |
putro yastvānuvarteta sa rājā pṛthivīpatiḥ |
bhavato'nunayāmyevaṃ pūrū rājye'bhiṣicyatām || 21 ||

"Yayati then said, 'Ye four orders with Brahmanas at their head, hear my words as to why my kingdom should not be given to my eldest son. My commands have been disobeyed by my eldest son, Yadu. The wise say that he is no son who disobeyeth his father. That son, however, who doth the bidding of his parents, who seeketh their good, who is agreeable to them, is indeed, the best of sons. I have been disregarded by Yadu and by Turvasu, too. Much I have been disregarded by Drahyu and by Anu also. By Puru alone hath my word been obeyed. By him have I been much regarded. Therefore, the youngest shall be my heir. He took my decrepitude. Indeed, Puru is my friend. He did what was so agreeable to me. It hath also been commanded by Sukra himself, the son of Kavi, that, that son of mine who should obey me will become king after me and bring the whole Earth under his sway. I, therefore, beseech thee, let Puru be installed on the throne.'
