diṣṭyā ca buddhirdharme te niviṣṭā pannagottama |
ato bhūyaśca te buddhirdharme bhavatu susthirā || 16 ||

"Unto Sesha who had said so, the Grandsire said, 'O Sesha, I know the behaviour of all thy brothers and their great danger owing to their offence against their mother. But O Snake, a remedy (for this) hath been provided by me even beforehand. It behoveth thee not to grieve for thy brothers. O Sesha, ask of me the boon thou desirest. I have been highly gratified with thee and I will grant thee today a boon. O best of snakes, it is fortunate that thy heart hath been set on virtue. Let thy heart be more and more firmly set on virtue.'
