Śatapatha Brāhmaṇa ("of a hundred paths") 11.8.4

Now, once upon a time, a tiger killed the samrâg-cow of those (who were sacrificing) with (the king of the) Kesin as their Grihapati. He (the king) said to his fellow-sacrificers, 'What atonement is there for this?' They replied, 'There is no atonement for this: Khandika Audbhâri alone knows an atonement for it; but he certainly desires as much as this, and worse than this, (to happen) to thee.'

He said, 'Charioteer, put to my horses; I shall drive thither: if so be he will tell me, I shall succeed (with my sacrifice); but if he will have me die, I shall be shattered along with the shattered sacrifice.'

Having put to the horses, he drove off, and came thither. When he (Khandika) saw him, he said, 'Seeing that there are those skins on deer, we break their ribs and cook them: the skin of the black antelope is attached to my neck --is it with thoughts such as these that thou hast dared to drive over to me?'

'Not so,' he replied; 'a tiger has killed my samrâg-cow, reverend sir; if so be thou wilt tell me, I shall succeed; but if thou wilt have me die, I shall be shattered along with the shattered sacrifice.'

He said, 'I will take counsel with my counsellors.' Having called them to counsel, he said, 'If I tell him, his race, not mine, will prevail here, but I shall gain the (other) world; and if I do not tell him, my own race, not his, will prevail here, but he will gain the (other) world.' They said, 'Do not tell him, reverend sir, for, surely, this (the earth) is the Kshatriya's world.' He replied, 'Nay, I will tell him: there are more nights up yonder.'

And, accordingly, he then said to him,--'Having offered the Spritis, he (the Adhvaryu) should say, "Drive up another (cow)!" and that one should be thy samrâg-cow.'--'[Having offered. with,] "From the moon I take thy mind, hail!--From the sun I take thine eye, hail!--From the wind I take thy breathings, hail!--From the regions I take thine ear, hail!--From the waters I take thy blood, hail!--From the earth I take thy body, hail!" let him then say, "Drive up another (cow)!" and that one shall be thy samrâg cow!' He then departed from thence, and, verily, members of the Kesin race are born here even to this day.
