यदज्ञानतो भाति विश्वं समस्तंविनष्टं च सद्यो यदात्मप्रबोधे ।मनोवागतीतं विशुद्धं विमुक्तंपरं ब्रह्म नित्यं तदेवाहमस्मि ॥ ४ ॥
In plain words
Not knowing it, you see a whole universe; and the moment that Self wakes to itself, the universe is gone on the spot. Past the reach of thought, past the reach of speech, utterly pure, utterly free, the supreme Brahman, eternal — that, and only that, is what I am.
Close to the Sanskrit
Through ignorance of which the entire universe appears, and which, upon the awakening to that Self, is instantly destroyed — beyond mind and speech, wholly pure, free, supreme Brahman, eternal: that alone I am.
