WHO WE ARE
90% of a mature tree is dead. Only [the cambium], the layer of trunk just inside the protective bark is alive. [This is where life flows through the tree.] Yet the dead central trunk obviously plays a vital role in keeping the tree standing upright. This suggests to me a metaphor…: there needs to be a certain [structure] in order to support us in working at the edge to create new growth.
