Matsyapurana 11.15

11.15

prāyo na mātā sāsmākaṃ śāpenāhaṃ yato hataḥ
devo 'pyāha yamaṃ bhūyaḥ kiṃ karomi mahāmate //

Hearing such a dreadful curse, Yama went to his father and told him that he had been cursed for no fault of his by his mother. In a childish freak, he lifted up his foot at her, at which in spite of the entreaties of Manu, she pronounced that curse upon him. Yama, continuing, said that such an attitude of Chhâyâ showed that she was not their mother. The Sun said, what could he do. Who does not get into trouble by committing an act of folly? What to say of others, even the omnipotent Lord Śiva had to reap the fruits of His actions. But, in spite of all that, he would give him a cock that would destroy all the worms of his foot and would also remove the blood and pus flowing from it.—13-17.
