In plain words
Whoever comes to know "I am the witness," sifting it out this way again and again — he is the one who is free, he is the one who knows. This is the drumbeat of Vedānta.
Close to the Sanskrit
He who should know, 'I am the witness,' having discriminated thus again and again — he alone is liberated, he is the knower: such is the drumbeat of Vedānta.
