Âditya (the sun) is Brahman, this is the doctrine, and this is the fuller account of it:— In the beginning this was non-existent. It became existent, it grew. It turned into an egg. The egg lay for the time of a year. The egg broke open. The two halves were one of silver, the other of gold.

In plain words: The sun should be worshipped as Brahman, the ultimate reality. In the beginning there was nothing; then something came to be and grew into an egg. After a year the egg broke into two halves, one silver and one gold.
