Now this is the Parikrī.
Khaṇḍika Audbhāri and Keśin Dārbhya contended among the Pañcālas.
Khaṇḍika sent a messenger to Keśin:
'He will sacrifice tomorrow with a Sadyaskrī.'
Now, having announced this, people sacrifice against a rival.
His Brahmins were Ahīnā Āśvatthi, Keśin Sātyakāmi, Gaṅginā Rāhakṣita, and Luśākapi Khārgali.
They came together to him.
He sat pondering.
They said to him, 'Why is the noble pondering?'
He said, 'Indeed, I have something to ponder.
You Brahmins teach: The Ādityas and the Aṅgirases contended for the heavenly world.
Those Ādityas went first to the heavenly world; the Aṅgirases were left behind.
He who, having announced this, sacrifices against a rival, he alone succeeds, his rival who hates him is defeated.'
