sa tatra samayaṃ cakre bhāryayā saha sattamaḥ |
vipriyaṃ me na kartavyaṃ na ca vācyaṃ kadācana || 7 ||

"Sauti continued, 'When the snake had promised, saying, 'I shall maintain my sister,' Jaratkaru then went to the snake's house. Then that first of mantra-knowing Brahmanas, observing rigid vows, that virtuous and veteran ascetic, took her hand presented to him according to shastric rites. And taking his bride with him, adored by the great Rishi, he entered the delightful chamber set apart for him by the king of the snakes. And in that chamber was a bed-stead covered with very valuable coverlets. And Jaratkaru lived there with his wife. And the excellent Rishi made an agreement with his wife, saying, 'Nothing must ever be done or said by thee that is against my liking. And in case of thy doing any such thing, I will leave thee and no longer continue to stay in thy house. Bear in mind these words that have been spoken by me.'
