[1029] "For there are serpents (bhogī) of yours born here— sons, and husband, and dependents; toward them, in speech and in deed, be you at all times free from malice. Thus, O nāgī, guard your freedom from malice in speech and in deed; having remained here in this palace (vimāna) for the full span of your life, you shall go from here upward to the heavenly world (devaloka)."
