"The fowler replied, 'O good Brahmana, Brahmanas are worthy of all respect from me. Listen, O sinless one, to this story of a previous existence of mine. O son of an excellent Brahmana, I was formerly a Brahmana, well-read in the Vedas, and an accomplished student of the Vedangas. Through my own fault I have been degraded to my present state. A certain king, accomplished in the science of dhanurveda (science of archery), was my friend; and from his companionship, O Brahmana, I, too became skilled in archery; and one day the king, in company with his ministers and followed by his best warriors, went out on a hunting expedition. He killed a large number of deer near a hermitage. I, too, O good Brahmana, discharged a terrible arrow. And a rishi was wounded by that arrow with its head bent out. He fell down upon the ground, and screaming loudly said, 'I have harmed no one, what sinful man has done this?' And, my lord, taking him for a deer, I went up to him and found that he was pierced through the body by my arrow. On account of my wicked deed I was sorely grieved (in mind). And then I said to that rishi of severe ascetic merit, who was loudly crying, lying upon the ground, 'I have done this unwittingly, O rishi.' And also this I said to the muni: 'Do thou think it proper to pardon all this transgression.' But, O Brahmana, the rishi, lashing himself into a fury, said to me, 'Thou shalt be born as a cruel fowler in the Sudra class."
