How is that possible?
 
The mind, when properly developed, is a very powerful instrument. If we can learn to focus our mental energy and project it towards others, it can have an effect upon them. You may have had an experience like this. Perhaps you are in a crowded room and you get this feeling that someone is watching you. You turn around and, sure enough, someone is staring at you. What has happened is that you have picked up that other person’s mental energy. Loving Kindness Meditation is like that. We project positive mental energy towards and it gradually transforms them.
