Mbh 3.132.3a

“Lomasa said, The sage Uddalaka had a disciple named Kahoda of subdued passions, and entirely devoted to the service of his preceptor and who had continued his studies long. The Brahmana had served his tutor long, and his preceptor, recognising his service, gave him his own daughter, Sujata, in marriage, as well as a mastery over the Shastras. And she became with child, radiant as fire. And the embryo addressed his father while employed in reading, ‘O father, thou hast been reading the whole night, but (of all that) thy reading doth not seem to me correct. Even in my fetal state I have, by thy favour, become versed in the Shastras and the Vedas with their several branches. I say, O father, that what proceeds from thy mouth, is not correct.’ Thus insulted in the presence of his disciples, the great sage in anger cursed his child in the womb, saying, ‘Because thou speakest thus even while in the womb, therefore thou shalt be crooked in eight parts of the body.’ The child was accordingly born crooked, and the great sage was ever after known by the name of Ashtavakra. Now, he had an uncle named Swetaketu who was the same age with himself. Afflicted by the growth of the child in the womb, Sujata, desirous of riches, conciliating her husband who had no wealth told him in private: ‘How shall I manage, O great sage, the tenth month of my pregnancy having come? Thou hast no substance whereby I may extricate myself from the exigencies, after I have been delivered.” Thus addressed by his wife, Kahoda went unto king Janaka for riches. He was there defeated in a controversy by Vandin, well versed in the science of arguments, and (in consequence) was immersed into water. And hearing that his son-in-law had been defeated in a controversy by Vandin and caused to be drowned by him, Uddalaka spake unto his daughter Sujata, saying, ‘Thou shall keep it a secret from Ashtavakra.’ She accordingly kept her counsel--so that Ashtavakra, when born, had heard nothing about the matter.
