Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Maharaja 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 Narayana, whose body was composed of golden effulgence and who resided within the sun. Maharaja Bharata worshiped Lord Narayana by chanting the hymns given in the Rg Veda, and he recited the following verse as the sun rose.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The predominating Deity within the sun is Hiranmaya, Lord Narayana. He is worshiped by the Gayatri mantra: om bhur bhuvah svah tat savitur varenyam bhargo devasya dhimahi. He is also worshiped by other hymns mentioned in the Rg Veda, for instance: dhyeyah sada savitr-mandala-madhya-varti. Within the sun, Lord Narayana is situated, and He has a golden hue.
