"The Brahmana said, 'In my younger days I had, through ignorance, stretched my hand (for acceptance of gifts). At present, however, I recite the Gayatri, observing the duty of abstention. Why dost thou, O king, tempt me thus, me who have for a long time observed the duty of abstention? I shall myself do what my duty is. I do not wish to have any share of the rewards won by thee, O monarch! I am devoted to penances and to study of the [paragraph continues] Vedas, and I have abstained from acceptance.'
