"Then Utanka waited on his preceptor. And his preceptor said, 'Thou art welcome! What hath occasioned thy long absence?' And Utanka replied to his preceptor, 'Sir, in the execution of this my business obstruction was offered by Takshaka, the King of serpents. Therefore I had to go to the region of the Nagas. There I saw two damsels sitting at a loom, weaving a fabric with black and white threads. Pray, what is that? There likewise I beheld a wheel with twelve spokes ceaselessly turned by six boys. What too doth that import? Who is also the man that I saw? And what the horse of extraordinary size likewise beheld by me? And when I was on the road I also saw a bull with a man mounted thereon, by whom I was endearingly accosted thus, 'Utanka, eat of the dung of this bull, which was also eaten by thy master?' So I ate of the dung of that bull according to his words. Who also is he? Therefore, enlightened by thee, I desire to hear all about them.'
