The saints were not people with the greatest education or even the largest results. But they did have a couple traits in common which were almost invisible: ehat they SAID correlated almost one hundred percent with what they WERE and what they DID. An amazing and invisible power may be released when a person's words and inner self finally match.
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.
