"When a young tree is injured it grows around that injury. As the tree continues to develop, the wound becomes relatively small in proportion to the size of the tree. The way a tree grows around its past contributes to its exquisite individuality, character, and beauty. I certainly don't advocate traumatization to build character, but since trauma is almost a given at some point in our lives, the image of the tree can be a valuable mirror."
