8.7.2

tad dhobhaye devāsurā anububudhire \
te hocur hanta tam ātmaānam anvecchāmo yam ātmānam anviṣya sarvāṃś ca lokān āpnoti sarvāṃś ca kāmān iti \
indro haiva devānām abhipravavrāja virocano 'surāṇām \
tau hāsaṃvidānāv eva samitpāṇī prajāpatisakāśam ājagmatuḥ \\807.2\

2. Then both the gods and the devils (deva-asura) heard it. Then they said: 'Come! Let us search out that Self, the Self by searching out whom one obtains all worlds and all desires!'

Then Indra from among the gods went forth unto him, and Virocana from among the devils. Then, without communicating with each other, the two came into the presence of Prajāpati, fuel in hand.
