In plain words
He is Vihāyasagati because the infinite sky is his ultimate abode and refuge, or because he is the sun. He is Jyoti because he shines by his own inherent light, as the Vedic verse proclaims Narayana to be the supreme light. He is Suruci because his splendor, brilliance, and divine will are all sublime. He is Hutabhuk because he receives and protects the oblations offered in every sacrifice. He is Vibhu because he pervades all things and rules the three worlds. He is Ravi because he draws up moisture as the sun. He is Virocana because he shines in myriad forms. He is Sūrya through the traditional grammatical derivation, and Savitā because he generates the entire cosmos. As the Vishnu Dharmottara declares: 'Ravi takes up moisture, and Savitā brings forth all beings.' He is Ravi because the sun serves as his divine eye.
