"there was in olden days a wise rishi of the name of utathya. he had a wife of the name mamata whom he dearly loved. one day utathya's younger brother brihaspati, the priest of the celestials, endued with great energy, approached mamata. the latter, however, told her husband's younger brother—that foremost of eloquent men—that she had conceived from her connection with his elder brother and that, therefore, he should not then seek for the consummation of his wishes. she continued, 'o illustrious brihaspati, the child that i have conceived has studied in his mother's womb the vedas with the six angas, seed is not lost in vain. how can then this womb of mine afford room for two children at a time? therefore, it behoveth thee not to seek for the consummation of thy desire at such a time. thus addressed by her, brihaspati, though possessed of great wisdom, could not suppress his desire. the child in the womb protested, 'there is no space here for two. o illustrious one, the room is small. i have occupied it first. it behoveth thee not to afflict me.' but brihaspati without listening to what that child in the womb said, sought the embraces of mamata possessing the most beautiful pair of eyes. and the illustrious brihaspati, beholding this, became indignant, and reproached utathya's child and cursed him, saying, 'because thou hast spoken to me in the way thou hast at a time of pleasure that is sought after by all creatures, perpetual darkness shall overtake thee.' and from this curse of the illustrious brihaspati, utathya's child who was equal unto brihaspati in energy, was born blind and came to be called dirghatamas (enveloped in perpetual darkness).
