And, O great king, I saw there the golden mountains of Meru and also Mahendra and those excellent mountains called the Vindhyas. And I beheld there the mountains of Malaya and of Paripatra also. These and many other mountains that are on earth were all seen by me in his stomach. And all these were decked with jewels and gems. And, O monarch, while wandering through his stomach, I also beheld lions and tigers and boars and, indeed, all other animals that are on earth, O great king! O tiger among men, having entered his stomach, as I wandered around, I also beheld the whole tribe of the gods with their chief Sakra, the Sadhyas, the Rudras, the Adityas, the Guhyakas, the Pitris, the Snakes and the Nagas, the feathery tribes, the Vasus, the Aswins, the Gandharvas, the Apsaras, the Yakshas, the Rishis, the hordes of the Daityas and the Danavas, and the Nagas also. O king, and the sons of Singhika and all the other enemies of the gods; indeed what else of mobile and immobile creatures may be seen on earth, were all seen by me, O monarch, within the stomach of that high-souled one. And, O lord, living upon fruits I dwelt within his body for many centuries wandering over the entire universe that is there. Never did I yet, O king, behold the limits of his body. And when, O lord of earth, I failed to measure the limits of that high-souled one’s body, even though I wandered within him continuously in great anxiety of mind. I then, in thought and deed sought the protection of that boon-giving and pre-eminent Deity, duly acknowledging his superiority. And when I had done this, O king, I was suddenly projected (from within his body) through that high-souled one’s open mouth by means, O chief of men, of a gust of wind. And, O king, I then beheld seated on the branch of that very banian that same Being of immeasurable energy, in the form of a boy with the mark of Sreevatsa (on his breast) having, O tiger among men, swallowed up the whole universe.
