brahmovāca |
tava bhāgaṃ kariṣyāmo makhamadhye yathā śṛṇu |
tena tvaṃ kuru kāryaṃ no viṣṇuṃ bodhaya māciram ||

Brahmâ said:-- We will give you, too, share in this our Yajña (sacrifice); so hear me; do our work and rouse Visnu from His sleep. During the time of performing Homa whatever ghee will fall outside the Homa-Kund (the sacrificial pit) will fall to your share; so be quick and do this.
