Then consider how the trees keep together. One tree, and yet its branches and its fruits and its flowers all turn in different directions. Every branch takes a different direction, and yet all keep together. What is it that directs the vigor and the strength of one branch and not the others in that direction, for they are all attached to the same tree-stem? Is it not that life-current which runs through it that directs their ways? As long as it runs through a tree it produces fruit and flowers.
