Translation: 
Mahārāja Bharata appeared very beautiful. He had a wealth of curly hair on his head, which was wet from bathing three times daily. He dressed in a deerskin. He worshiped Lord Nārāyaṇa, whose body was composed of golden effulgence and who resided within the sun. Mahārāja Bharata worshiped Lord Nārāyaṇa by chanting the hymns given in the Ṛg Veda, and he recited the following verse as the sun rose.
Purport: 

The predominating Deity within the sun is Hiraṇmaya, Lord Nārāyaṇa. He is worshiped by the Gāyatrī mantra: om bhūr bhuvaḥ svaḥ tat savitur vareṇyaṁ bhargo devasya dhīmahi. He is also worshiped by other hymns mentioned in the Ṛg Veda, for instance: dhyeyaḥ sadā savitṛ-maṇḍala-madhya-vartī. Within the sun, Lord Nārāyaṇa is situated, and He has a golden hue.
