Learn the words of wisdom uttered by the wise and apply them in your own life. Live them - but do not a make a show of reciting them, for he who repeats what he does not understand is no better than an ass loaded with books.
The reality of the other person is not in what he reveals to you, but in what he cannot reveal to you. Therefore, if you would understand him, listen not to what he says but rather to what he does not say.
