It has been said that when words come from the heart, they go straight to the heart. And that when they come from the tongue, they go no further than the ears.
It is quite true that there are two types of utterances. One is when one says whatever comes into one’s head, on the spur of the moment or to get by. This is an utterance that comes from the tongue. It emanates from the surface of the speaker. That is why it does not penetrate further than the surface of the listener.
The other type of utterance is one that springs from serious thought. A person has really and truly discovered something and in all earnestness puts it in words. Such words come from the depths of the speaker’s heart and that is where they find their way in the listener—right to the depths of his heart.
When an utterance of this nature comes out of one, it is bound to cast its stamp on others besides oneself.
