'He who meditates on fire as Brahman, obtains, resplendent himself, resplendent worlds, full of light and free of darkness; he is, as it were, lord and master as far as fire reaches—he who meditates on fire as Brahman.' 'Sir, is there something better than fire?' 'Yes, there is something better than fire.' 'Sir, tell it me.'

In plain words: Whoever meditates on fire as Brahman (the highest reality) becomes bright and reaches bright worlds with no darkness. Narada asks if there is something greater than fire, and the teacher says yes.
