The sun-god marks the path of liberation, which is called arciradi-vartma. He is the chief source for understanding of the Vedas, he is the abode where the Absolute Truth can be worshiped, He is the gateway to liberation, and he is the source of eternal life as well as the cause of death. The sun-god is the eye of the Lord. May that Supreme Lord, who is supremely opulent, be pleased with us.
