The Great Epic of the Bhārata dynasty 3.294.10

3.294.10

sahajaṃ varma me vipra kuṇḍale cāmṛtodbhave |
tenāvadhyo'smi lokeṣu tato naitaddadāmyaham || 10 ||

Vaisampayana continued, "Although thus urged with various words by Karna, still, O chief of the Bharata race, that Brahmana did not ask for any other boon. And although Karna sought to pacify him to the best of his power, and worshipped him duly, yet that best of Brahmanas did not ask for any other boon. And when that foremost of Brahmanas did not ask for any other boon, Radha's son again spake unto him with a smile, 'My mail, O regenerate one, hath been born with my body, and this pair of ear-rings hath arisen from Amrita. It is for these that I am unslayable in the worlds. Therefore, I cannot part with them. Do thou, O bull among Brahmanas, accept from me the entire kingdom of the earth, rid of enemies and full of prosperity! O foremost of regenerate ones, if I am deprived of my ear-rings, and the mail born with my body, I shall be liable to be vanquished by the foes!'
