In plain words
Ignorance is the root of it all — so ignorance is exactly what has to go. That is why the knowledge of Brahman is taken up here; and out of that knowledge comes the highest good there is.
Close to the Sanskrit
Ignorance would be its root — thus, the removal of that is what is sought. Hence the knowledge of Brahman is begun; from that the highest good would come to be.
