And he prostrated himself thereupon at the feet of Bhava, and the god also was pleased with him. And Hara, beholding the
wonder of Arjuna and seeing that his body had been emaciated with ascetic austerities, spake unto him
in a voice deep as the roaring of the clouds, saying, 'O Phalguna, I have been pleased with thee for thy
act is without a parallel. There is no Kshatriya who is equal to thee in courage, and patience. And, O
sinless one, thy strength and prowess are almost equal to mine. O mighty-armed one, I have been
pleased with thee. Behold me, O bull of the Bharata race! O large-eyed one! I will grant thee eyes (to see
me in my true form). Thou wert a Rishi before. Thou wilt vanquish all thy foes, even the dwellers of
heaven; I will as I have been pleased with thee, grant thee an irresistible weapon. Soon shall thou be able
to wield that weapon of mine."
