People say to you, 'you've changed', or something like that. Well, I hope, for the sake of God, that I have changed, because I don't want to be the same person all my life. I want to be growing, I want to be expanding. I want to be changing. Because animate things change, inanimate things don't change. Dead things don't change. And the heart should be alive, it should be changing, it should be moving, it should be growing and its knowledge should be expanding.
