When they were in hiding, the Pandavas came to the river Ganga one night. A warrior came riding in his chariot and shouted, "I am Angarparna, a heavenly being. This part of the forest belongs to me. You can't cross the river here." Arjuna said, "Sacred river Ganga is nobody's property." Angry Angarparna roared, "You have no idea how strong I am. "Now Arjuna was also angry, he said, "You have never fought with a true warrior. I challenge you to a fight. Hearing this Angaparna attacked Arjuna with his sword. Arjuna escaped his blow and threw at him the burning mashaal (torch) that he held. It landed on Angaparna chariot and fainted. When Angaparna came to his senses he begged for forgiveness. Forgiven by the Pandavas, he presented them with chakhushi, thedivine sight by which they could see anything at any place and at any time.
