The eastern rays of the sun are the honey-cells in front. The Rik verses are the bees, the Rig-veda (sacrifice) is the flower, the water (of the sacrificial libations) is the nectar (of the flower).

In plain words: The sun's eastern rays are like honeycomb cells. The verses of the Rig Veda, the oldest holy book, are the bees. The Rig Veda ritual is the flower, and the water poured in offering is its nectar.
