In plain words
Say the doer really did experience it — 'I am free.' It still does not work. Freedom from pleasure and pain cannot hold in the I-who-acts.
Close to the Sanskrit
If liberation were experienced by the agent thus, as 'I,' [still] complete release from pleasure and pain is not tenable in the I-agent.
