Mbh 1.3.32

“And Utanka being told this, said unto the Queen, ‘Lady, be under no apprehension. Takshaka, Chief of the serpents, is not able to overtake me.’ And having said this, and taking leave of the Queen, he went back into the presence of Paushya, and said, ‘Paushya, I am gratified.’ Then Paushya said to Utanka, ‘A fit object of charity can only be had at long intervals. Thou art a qualified guest, therefore do I desire to perform a sraddha. Tarry thou a little. And Utanka replied, ‘Yes, I will tarry, and beg that the clean provisions that are ready may be soon brought in.’ And the king having signified his assent, entertained Utanka duly. And Utanka seeing that the food placed before him had hair in it, and also that it was cold, thought it unclean. And he said unto Paushya, ‘Thou givest me food that is unclean, therefore shalt thou lose thy sight.’ And Paushya in answer said, ‘And because dost thou impute uncleanliness to food that is clean, therefore shalt thou be without issue.’ And Utanka thereupon rejoined, ‘It behoveth thee not, after having offered me unclean food, to curse me in return. Satisfy thyself by ocular proof.’
