। ॥ ४४० ॥
In plain words
His wisdom never lets him draw a line between himself and Brahman, or between Brahman and the world that arises from it. No divide, anywhere, ever. That is the one called liberated while still alive.
Close to the Sanskrit
He who, through wisdom, never discerns any difference between the individual Self and Brahman, nor between Brahman and creation — he is regarded as liberated-while-living.
