Balancing your ego with a sense for the unity of our universe is often a matter of seeing the right illustration of the facts. A story that resonated highly with me was told by a monk who once confronted a person that thought a little bit too much of himself and needed no one. The monk pointed at a nearby tree and explained how the man's lungs could not function without trees and plants doing the reverse, turning carbon dioxide into oxygen. The mirror images of leaves and lungs could only co-exist because of each other.
Steve Jobs often sent e-mails to himself to capture what was on his mind. In a recent release of some documents from his family, one of these e-mails reminded me of the lungs & leaves story.
Accepting our dependencies might be a great step. Loving them might even be more joyous.
