It has been said, ‘Āditya (Sun) is Brahman.’ Now this is being explained: This universe was at first non-existent, being without names and forms. (It was not visible, but it existed in a subtle form). Slowly it manifested itself, as a shoot comes out of a seed. Next it developed into an egg and remained for a whole year like that. It then split in two, one half becoming silver and the other half becoming gold.
Of these two parts of the egg, the one that is silver is this earth, and the one that is gold is space. The thick membranes are the mountains. The thin membranes are the clouds and mist. The veins are the rivers, and the fluid in the bladder is the ocean.
Then that which was born was the sun. Its appearance was greeted by joyous sounds from all beings, and many desirable things appeared. Since then, the sunrise and the sunset are both marked by joyous sounds from all beings, and many enjoyable things also appear at that time.
One who knows the sun as Brahman and worships it as such very soon hears sounds pleasing to the ears and also has many good things to enjoy.
