In the Brahma-saṁhitā (BS 5.38), the sun is described as the eye of the Supreme Personality of Godhead.
- yac-cakṣur eṣa savitā sakala-grahāṇāṁ
- rājā samasta-sura-mūrtir aśeṣa-tejāḥ
- yasyājñayā bhramati sambhṛta-kāla-cakro
- govindam ādi-puruṣaṁ tam ahaṁ bhajāmi
As the sun arises, one should chant the Vedic mantra beginning with the Gāyatrī. The sun is the symbolic representation of the eyes of the Supreme Lord. Mahārāja Bharata lamented that although the sun was going to set, due to the poor animal's absence, he could not find anything auspicious. Bharata Mahārāja considered himself most unfortunate, for due to the animal's absence, there was nothing auspicious for him in the presence of the sun.
