In plain words
The poet: Who ate the customary offering laid out for Indra, heaped up like the great Himālaya, and then protected the cowherds? Who founded the creeds the scriptures teach, and who guards them? Who guards the dark-throated one [Śiva] together with the four-faced one [Brahmā], and who swallowed the worlds together with all their creatures? Who but the Lord?
