Words are words. After all, they mean nothing, unless there is something behind. Have you never noticed that when you speak to certain people, you may express yourself quite clearly and yet they understand nothing; and to others you say just two words and they understand immediately? You have not had this experience? No? I have had it often. Therefore, it does not depend upon the external form, the words one speaks, but on the force of the thought one puts into them; and the greater, stronger, more precise and clear the thought-force, the more the chance of what you say being understood by people who are able to receive that force. But if one speaks without thinking, usually it is impossible to understand what he says. It makes a kind of noise, that is all. For example, when you have the habit of speaking with someone, exchanging ideas with him, when between the two of you there is a certain mental adjustment, that is, when you have taken the precaution of saying, “When I use this word, I mean this”, and the other person has said, “When I use that word, I mean that”, and so on; when you are used to an interchange, when you have established a kind of contact between brain and brain—even if it be only that—you understand each other quite easily. But with people who come altogether from elsewhere, with whom you have never spoken, you need a little time to adjust and adapt yourself to understand what they mean by the words they use…. What is it that makes you understand? It is just the kind of mental sense that is behind the words. When the thought is strongly thought out, there is a powerful vibration and it is that which is sensed; the word is only an intermediary means. You can develop this sense to the point of having a direct mental contact with a minimum of words or even without any words at all; but then you must have a very great force of thought-concentration. And for everything one does, it is like that. When there is a developed consciousness behind, when one has the power to concentrate it, one can do anything at all—this consciousness will act.
