In plain words
Without the direct inner conviction 'I am existence', even the great teaching 'You are That' remains empty. It only yields its true meaning to one who clearly discriminates between the objective and subjective.
Close to the Sanskrit
In the absence of the intellect's thought 'I am existent', even [the statement] 'That thou art' would be meaningless; for one who knows the discrimination of the you and the I, this word is meaningful.
