Week 13: Reading Wednesday

 Krishna Humbles Arjuna

Arjuna approaches Rama's bridge in Rameshwaram and wonders why Rama did not use arrows to build the bridge. A monkey mocks him and challenges Arjuna to build a bridge of arrows that will support his weight. Arjuna fails to do so as any bridge he builts is toppled by the monkey with one touch. When Arjuna decides to give up and immolate himself, as the terms of the bet were, a mysterious boy appears. He asks for a redo of the trial with a witness. Arjuna succeeds and the monkey reveals itself to be Hanuman. The boy reveals himself to be Lord Krishna. Both Arjuna and Hanuman worship him as Lord Vishnu. Hence, Hanuman is on Arjuna's flag in his chariot.
