एतस्मिन्न अन्तरे स शरमणस तवरमाण उपसृत्य ते कुण्डले गृहीत्वा पराद्रवत तम उत्तङ्कॊ ऽभिसृत्य जग्राह स तद रूपं विहाय तक्षक रूपं कृत्वा सहसा धरण्यां विवृतं महाबिलं विवेश ।। १-३-१३७ ।।

sanskrit

'In the meantime, the beggar came quickly to the spot and taking up the ear-rings ran away. And Utanka having completed his ablutions in water and purified himself and having also reverently bowed down to the gods and his spiritual masters pursued the thief with the utmost speed. And having with great difficulty overtaken him, he seized him by force. But at that instant the person seized, quitting the form of a beggar and assuming his real form, viz., that of Takshaka, speedily entered a large hole open in the ground. And having got in, Takshaka proceeded to his abode, the region of the serpents.' ।। 1-3-137 ।।
