Mbh 12.304.1a

"'"Vasishtha said, 'Thus in consequence of his forgetfulness the Soul follows ignorance and obtains thousands of bodies one after another. He attains to thousands of births among the intermediate orders and sometimes among the very gods in consequence of his union with (particular) attributes and the puissance of attributes.[1615] From the status of humanity, he goes to heaven and from heaven he comes back to humanity, and from humanity he sinks into hell for many long years. As the worm that fabricates the cocoon shuts itself, completely on every side by means of the threads it weaves itself, even so the Soul, though in reality transcending all attributes, invests himself on every side with attributes (and deprives himself of liberty).[1616] Though transcending (in his real nature) both happiness and misery, it is thus that he subjects himself to happiness and misery. It is thus also that, though transcending all diseases, the Soul regards himself to be afflicted by headache and opthalmia and toothache and affections of the throat and abdominal dropsy, and burning thirst, and enlargement of glands, and cholera, and vitiligo, and leprosy, and burns, and asthma and phthisis, and epilepsy, and whatever other diseases of diverse kinds are seen in the bodies of embodied creatures. Regarding himself, through error, as born among thousands of creatures in the intermediate orders of being, and sometimes among the gods, he endures misery and enjoys the fruits of his good deeds.
