Jaiminīya (Talavakāra) Brāhmaṇa 1.55

having raked out the hot ashes of the Gārhapatya [fire], he should pour it out silently in them. That is neither offered nor un-offered. He should pour water after it; with water indeed he reaches it. Then with whatever else he finds, with that he should offer. Now they also say: If the milked [milk] should become impure, what is the action in that case? What is the expiation? On whatever embers he was going to place it, having pushed them back, on them he should pour it out silently. That is neither offered nor un-offered. He should pour water after it; with water indeed he reaches it. Then with whatever else he finds, with that he should offer. Now they also say: If it should become impure while set on [the fire], what is the action in that case? What is the expiation? On whatever embers it was set, having pushed them back, on them he should pour it out silently. That is neither offered nor un-offered. In that he pours it on them, by that it is offered; and in that he puts them out, by that it is un-offered. He should pour water after it; with water indeed he reaches it. Then with whatever else he finds, with that he should offer. Now they also say:

— if it should become impure when he has run forward, what is the action in that case? What is the expiation?

And on that point some think: 'It must indeed be offered,' saying: 'This has departed; for this, non-offering is not suitable.'

Then some, having poured water on it, pour it away.

One should not do it in that way.

If someone there should say: 'Turned away, this one poured away this fire-offering; this sacrificer will be poured away,'

it would surely be so.
