Mbh 1.104.4b

And from this curse of the illustrious Vrishaspati Utathya’s child who was equal unto Vrihaspati in energy, was born blind and came to be called Dirghatamas (enveloped in perpetual darkness). And the wise Dirghatamas, possessed of a knowledge of the Vedas, though born blind, succeeded yet by virtue of his learning, in obtaining for a wife a young and handsome Brahmana maiden of the name of Pradweshi. And having married her, the illustrious Dirghatamas, for the expansion of Utathya’s race, begat upon her several children with Gautama as their eldest. These children, however, were all given to covetousness and folly. The virtuous and illustrious Dirghatamas possessing complete mastery over the Vedas, soon after learnt from Surabhi’s son the practices of their order and fearlessly betook himself to those practices, regarding them with reverence. (For shame is the creature of sin and can never be where there is purity of intention). Then those best of Munis that dwelt in the same asylum, beholding him transgress the limits of propriety became indignant, seeing sin where sin was not. And they said, ‘O, this man, transgresseth the limit of propriety. No longer doth he deserve a place amongst us. Therefore, shall we all cast this sinful wretch off.’ And they said many other things regarding the Muni Dirghatamas. And his wife, too, having obtained children, became indignant with him.
