Concentration is not awareness, and the person of concentration will never show compassion. Compassion is not a consequence of concentration. Concentration means the focusing of the mind, the narrowing of the mind on only one point. The concentrated mind becomes a very powerful mind — but remember it is mind, and very powerful, hence more dangerous than ever. Concentration is the method of science.
Awareness is totally different; it is not focusing, it is unfocused alertness. For example, right now you are listening to me. You can hear in a concentrated way, you can be focused on me; then you will miss the birds and their songs, then you will miss this noise on the road. Then you are not aware, then your mind has become very narrow. Awareness is not the narrowing of the mind but the disappearance of the mind. The narrowing of the mind makes the mind more of a mind.
