I think that those who serve most potently, work on levels of consciousness that have to do with radiating love — maybe God's love... It is important that you have a brain and use it, but that is secondary. The basic premise is that you allow something to come through you. Then you use your intelligence to give your heart's work discipline and logic. But the transformative energy, that which can change events, that heals, that helps, that serves, comes from somewhere deep inside.
When I was in Italy, Mme. Montessori told me that besides all the activities she gives to children, she encourages them to keep silence; and after a little time, they like it so much that they prefer silence to their activity. And it interested me to see a little girl of about six years of age, when the time of silence came, went and closed the windows and door, and put away all the things that she was playing with. Then she came and sat in her little chair and closed her eyes, and she did not open them for about three or four minutes. It seemed she preferred those five minutes of silence to all the playing of the whole day.
