Verse 185

रूपाण्येव यस्यायतनं चक्षुर्लोको मनो-ज्योतिर्यो वै तं पुरुषं विद्यात्सर्वस्यात्मनःपरायणँ स वै वेदिता स्यात् ।याज्ञव-ल्क्य वेद वा अहं तं पुरुषँ सर्वस्यात्मनःपरायणं यमात्थ य एवासावादित्ये पुरुषःस एष वदैव शाकल्य तस्य का देवतेतिसत्यमिति होवाच ॥ १२ ॥

In plain words

Forms are his home, the eye his world, the mind his light. Know that person and you have reached the final resting place of every self there is. Yajnavalkya doesn't flinch: I know him. He's the person standing right there inside the sun — the very one you're pointing to, Shakalya. Go on, ask. What god does he answer to? Truth, he says.

Close to the Sanskrit

'Forms alone are his abode', the eye his world, the mind his light — whoever should know that person as the final resort of the self of all, he would indeed be a knower. Yājñavalkya: I know that person, the final resort of the self of all, of whom you speak — the one who is that very person yonder in the sun. He is this very one, Śākalya; speak on! Of him, what is the deity? — 'Truth', he said.
