When I asked my teacher, "What is the sign of a real guru?", he replied; "It is not his form, it is not his appearance, it is not what he says. It is his atmosphere, it is what his presence conveys to you, it is what his atmosphere tells you. That which he may say, that is nothing." So there is the saying in the English language, "Actions speak louder than words;" or; "That which you are speaks louder than what you say."
