Mbh 12.141.3a

"'"The Chandala said, 'Who is there, engaged in undoing the latch? The whole Chandala hamlet is asleep. I, however, am awake and not asleep. Whoever thou art, thou art about to be slain.' These were the harsh words that greeted the sage's ears. Filled with fear, his face crimson with blushes of shame, and his heart agitated by anxiety caused by that act of theft which he had attempted, he answered, saying, 'O thou that art blest with a long life, I am Viswamitra. I have come here oppressed by the pangs of hunger. O thou of righteous understanding, do not slay me, if thy sight be clear.' Hearing these words of that great Rishi of cleansed soul, the Chandala rose up in terror from his bed and approached the sage.

One solicitous of food has no shame. It is hunger that is urging me to this misdeed. It is for this that I desire to take away that haunch of dog's meat. My life-breaths are languishing. Hunger has destroyed my Vedic lore. I am weak and have lost my senses. I have no scruple about clean or unclean food.

After I had failed to obtain any alms, having wandered from house to house in this your hamlet, I set my heart upon this sinful act of taking away this haunch of dog's meat.

Know that I have now become even like him in that respect.' Hearing these words of the great Rishi, the Chandala answered him, saying, 'Listen to me.
