Aitareyabrahmana 7.26

7.26

Now next as to the sacrificer's portion:
Regarding this they say: ‘Should a kṣatriya consume the sacrificer's portion, or should he not consume it?’
If he should consume it, he would consume what is offered after what is unoffered, and become the worse for it;
if he should not consume it, he would exclude himself from the sacrifice, for the sacrificer's portion is indeed the sacrifice.
It is to be handed over to the brahman priest.
For this brahman priest is the place of the purohita for the kṣatriya;
indeed, the purohita is half of the kṣatriya's self.
Thus he invisibly attains the form of one who has consumed it;
it does not become visibly consumed by him.
For visibly the sacrifice is this: the brahman priest.
For the whole sacrifice is founded upon the brahman priest, and the sacrificer is founded upon the sacrifice.
Thereby they pour sacrifice into sacrifice, as water into water, as fire into fire.
That indeed does not become an excess; that does not harm him.
Therefore it is to be handed over to the brahman priest.
Some offer it in the fire, saying:
‘There is a world of Prajāpati named Vibhān; therein I place you together with the sacrificer, svāhā!’
One should not do so.
For the sacrificer is the sacrificer's portion; he would cast the sacrificer into the fire.
If anyone were to say of him there:
‘You have cast the sacrificer into the fire; the fire will burn his vital breaths,
the sacrificer will die’—
it would surely be so.
Therefore he should not entertain any hope for it; he should not entertain any hope.
