In plain words
The purpose of the narrative opening with 'both those' has been explained. As tradition tells us, when Prajāpati's declaration reached the devas and asuras through traditional transmission, they wondered what to do. In their respective assemblies, the gods and demons said to one another: 'Come, if you agree, let us seek that Self, let us find that very Self by which one attains all worlds and all desires.' With this resolve, Indra, king of the gods, leaving behind all other deities and every luxury, set out toward Prajāpati carrying nothing but his physical body. Virocana did likewise for the asuras. This shows that teachers must be approached with humility, and that spiritual wisdom surpasses the sovereignty of the three worlds; for these two royal leaders, accustomed to every indulgence, sought the preceptor in this spirit. Without communicating with one another, each concealing a secret rivalry for the prize of knowledge, they arrived before Prajāpati with sacrificial fuel in their hands.
Close to the Sanskrit
That the purpose of the narrative beginning with 'and both those' has been stated. Indeed, that declaration of Prajāpati—that both gods and demons, the devas and the asuras, having heard and understood the tradition handed down in succession, did what?—is stated: those gods and demons spoke to one another in their respective assemblies: 'Well now, if you agree, let us seek that Self, let us make the quest for that Self by which one attains all worlds and all desires.' Saying this, Indra himself, as king, having left behind all the other gods and all articles of enjoyment, journeyed forth to Prajāpati with his physical body alone; and similarly Virocana for the asuras. This demonstrates that teachers are to be approached with humility, and that knowledge is greater than the sovereignty of the three worlds, since both royal leaders of gods and demons, though worthy of great enjoyments, thus approached the preceptor. Those two, indeed, without communicating with one another, without making a mutual pact, displaying mutual envy regarding the fruit of knowledge, holding sacrificial fuel and bundles of fuel in their hands, arrived near Prajāpati.
