The northern rays of the sun are the honey-cells on the left. The (hymns of the) Atharvâṅgiras are the bees, the Itihâsa-purâna (the reading of the old stories) is the flower, the water is the nectar.
Those very hymns of the Atharvâṅgiras (as bees) brooded over the Itihâsa-purâna; and from it, thus brooded on, sprang as its (nectar) essence, fame, glory of countenance, vigour, strength, and health.
That flowed forth, and went towards the sun. And that forms what we call the extreme dark (parah krishnam) light of the sun.
