ज्ञानेन यद्विद्वान् पश्यति ब्रह्म, तत् किं शुक्लमिव आभाति, लोहितमिव आभाति, कृष्णमिव अर्जुनं काद्रवमिव आभाति; यत्र देशे भाति कथंरूपं तदमृतमक्षरं परं ब्रह्म ॥
In plain words
The Brahman a knower sees through knowledge — what does it look like? Does it shine out white? Does it shine out red? Black, or silver, or dun-brown? And where is it, in what place does it shine, and what form does it wear — that deathless, imperishable, supreme Brahman?
Close to the Sanskrit
That Brahman which the knower sees by knowledge — does that shine as if white? Does it shine as if red? Does it shine as if black, as if silver-bright, as if tawny? In what place does it shine, and having what form is that deathless, imperishable, supreme Brahman?
