Ramana answers: "How do you know I am not doing it? Does preaching consist of mounting a platform and haranguing the people around? Preaching is a simple communication of knowledge, it can really be done in Silence only. What do you think of a man who listens to a sermon for an hour or so and goes away without having been impressed by it enough to have changed his life? Compare him to another who sits in a Holy Presence and goes away after some time with his outlook on life totally changed. Which is better, to preach loudly without effect or to sit Silently and send out Inner Force?"
