Mbh 3.215.1a

“The fowler continued, ‘Thus cursed by that rishi, I sought to propitiate him with these words: ‘Pardon me, O muni, I have done this wicked deed unwittingly. It behooves thee to pardon all that. Do thou, worshipful sir, soothe yourself.’ The rishi replied, ‘The curse that I have pronounced can never be falsified, this is certain. But from kindness towards thee, I shall do thee a favour. Though born in the Sudra class thou shalt remain a pious man and thou shalt undoubtedly honour thy parents; and by honouring them thou shalt attain great spiritual perfection; thou shalt also remember the events of thy past life and shalt go to heaven; and on the expiation of this curse, thou shalt again become a Brahmana. O best of men, thus, of old was I cursed by that rishi of severe power, and thus was he propitiated by me. Then, O good Brahmana, I extricated the arrow from his body, and took him into the hermitage, but he was not deprived of his life (recovered). O good Brahmana, I have thus described to thee what happened to me of old, and also how I can go to heaven hereafter.’ The Brahmana said, ‘O thou of great intelligence, all men are thus subject to happiness or misery, thou shouldst not therefore grieve for that. In obedience to the customs of thy (present) race, thou hast pursued these wicked ways, but thou art always devoted to virtue and versed in the ways and mysteries of the world. And, O learned man, these being the duties of thy profession, the stain of evil karma will not attach to thee. And after dwelling here for some little time, thou shalt again become a Brahmana; and even now, I consider thee to be a Brahmana, there is no doubt about this. For the Brahmana who is vain and haughty, who is addicted to vices and wedded to evil and degrading practices, is like a Sudra. On the other hand, I consider a Sudra who is always adorned with these virtues,--righteousness, self-restraint, and truthfulness,--as a Brahmana.
