Jaiminīya (Talavakāra) Brāhmaṇa 2-4.143

2-4.143

Now the Satrāsāhīya is for victory:
'May he entirely overpower him who is to be overpowered by him.'
Then the Utsedhaniṣedha [sāmans] are for the rising and repressing of the worse and the better.
Then the Viśoviśīya and the Sadoviśīya:
By means of the Viśoviśīya, Indra mounted over the gods;
he made them into subjects with the Sadoviśīya, thinking, 'Let them be subjects in the sadas.'
Then these are Triṣṭubhs.
Upon them is the Brahmasāman.
The Brahmasāman is spiritual power;
the Triṣṭubh is royal power.
The Brahmasāman is indeed the sacrificer's desire.
They fulfill the sacrificer's desires in his own domain.
