Jaiminīya (Talavakāra) Brāhmaṇa 33.201

They conquered him. Approaching him a second and a third time, he said, 'Let me officiate for you in sacrifice.' He said, 'Indeed, they do not sacrifice here. Whoever sacrifices here, him they would conquer. Twice has he sacrificed; they just conquered that one.' He showed him world after world, [saying,] 'Having sacrificed, one wins this world, and this.' He reflected: 'Even if they conquer that one, come, let me sacrifice!' He said to him, 'Officiate for me!' He officiated for him. The sadas hall and the havirdhāna shed arose of their own accord; he pressed Soma in a mortar. He said, 'For whom did you sacrifice?' 'For Upagu.' Rising up himself, cutting him down, he threw him into the water.

His father Suśravas Sthaurāyaṇa realized: 'Kutsa Aurava has indeed my son

cut down and cast into the water.'

Running up to him, he said, 'Where have you put my son?'

'Here he lies, cast into the water.'

He went down after him.

Indra, having become a red deer, drank the Soma out of his mouth.

He reflected: 'This is indeed Indra.

Let me praise just him;

he will bring this [son] of mine back together.'

He saw this sāman.
