If every man is a tree, then his body is the trunk, his mind are the leaves and his soul are the roots. Without enough leaves a tree will not have enough energy to grow; however if there are too many leaves, the tree will become top-heavy and fall. If its trunk is too small then it will bend to the smallest breeze, but if the trunk is too brittle then in a song storm, the it will snap. If the roots are not planted well enough in the ground, then any force can uproot the tree. You must be balanced in mind, body, and soul in order to yield the best fruit.
