1.3.27

pratyāha \ mātā rudrāṇāṃ duhitā vasūnāṃ svasādityānāmamṛtasya nābhiḥ \ pranuvocañcikituṣe janāya māgāmanāgāmaditiṃ vadhiṣṭa \ mama cāmuṣya ca pāpmānaṃ hanomīti yadyālabheta \27\

He replies, 'The mother of the Rudras, the daughter of the Vasus, the sister of the Âdityas, the navel of immortality. To the people who understand me, I say, "Do not kill the guiltless cow, which is Aditi." I kill my sin and N.N.'s sin,'—thus, if he chooses to have it killed.
