मुकुरस्थं मुखं यद्वन्मुखवत्प्रथते मृषा ।बुद्धिस्थाभासकस्तद्वदात्मवत्प्रथते मृषा ॥ ६३ ॥
In plain words
The face in the mirror spreads out as a face — falsely. Just so, the shining that sits inside the intellect spreads out as the ātman — falsely.
Close to the Sanskrit
Just as the face situated in a mirror spreads forth falsely as if it were a face, so the appearer situated in the intellect spreads forth falsely as if it were the Self.
