I went to see Patch Adams speak last night. I had seen him speak about 10 years ago. It was completely amazing. I wish I could even give you some clue as to what it was like, but I couldn't possibly begin to reiterate what he said. It was completely moving. In addition to speaking about the health care issue in America, he spoke about loving.
His answer to the violence and atrocities in the world is for everyone to simply love everyone else. It's so simplistic in design, but what a profound difference it would make in the world if this really happened. He suggested that everyone just sit for five minutes and really really imagine what it would be like if we truly loved everyone. Despite differences and things we don't like, but looking past that and truly loving people.
If you ever have a chance to see him speak, I reccommend it. It is truly life changing if you allow it to be.
