The sun over there is honey to the gods. Space is the crossbeam, the mid-region is the beehive, and the rays are the eggs.
The rays of the sun in the east are the eastern honey-cells (of the beehive). The Ṛk mantras are the bees, and the Ṛg Veda is the flower. The water (from the sacrifice, such as the soma juice and other things) is the nectar (of the flower). These Ṛk mantras—
—stimulated this Ṛg Veda. Out of that Ṛg Veda so stimulated came fame, vitality, the power of the organs, energy, and the essence of food.
All this (fame, etc.) spread out to the sun and took shelter there. It is this, that accounts for the red look of the sun.
