The sun-god evaporates water from the seas and oceans and then forms the water into clouds and distributes it over land. When there is sufficient rainfall grains are produced, and these grains maintain living entities in each and every planet. The sun-god is also addressed herein as pūrṇa, or complete, because the rays emanating from the sun have no end. For millions and millions of years since the creation of this universe, the sun-god has been supplying heat and light without diminution.
