Parāçara said:—O Maitreya, hear what you have asked The sun, though at one with seven beings in his orbit, is separate from them being their head. The whole and great energy of Vishnu, which is called the three Vedas,—Rich Yajush and Sāman lightens the whole universe and destroys its iniquity. This energy exists as Vishnu for the preservation of the universe and abiding as the three Vedas within the sun. And wherever in every month the sun exists there is the Vishnu-energy composed of the three Vedas. The Richas shine in the morning, the hymns of Yajush at noon and Vrihadrathantara and other portions of the Sāman in the afternoon. This threefold manifestation of Vishnu designated under the three Vedas is the energy of Vishnu that Influences the divine positions of the sun.
