Passage 2

स होवाच बालाकिर्य एवैष आदित्ये पुरुषस्तमेवाहमुपास इति तं होवाचाजातशत्रुर्मा मैतस्मिन्समवादयिष्ठाः ।बृहत्पाण्डरवासा अतिष्ठाः सर्वेषां भूतानां मूर्धेति वा अहमेतमुपास इति स यो हैतमेवमुपास्तेऽतिष्ठाः सर्वेषां भूतानां मूर्धा भवति ॥ २ ॥

In plain words

Bālāki said, "The person who is in the sun — him indeed I worship." Ajātaśatru said to him, "Do not draw me into talk about him. I worship him as the great one, clad in white, the surpassing one, the head of all beings." He who worships him thus becomes surpassing, the head of all beings.
