We can see the same thing in different aspects of life. For instance the falls and springs of water, the different channels, all show one big central current of water, which scatters as it falls. It touches different rocks, spreads into many streams, and yet ultimately unites again. In vegetable life we see the same. A tree with fruit and flowers and so many leaves and branches has yet one central part of its being: its stem. The life of the stem is the life of the whole tree. It is not so much that the fruits and other forms appear upon the tree as that the stem itself is repeated over and over again. Every branch is a stem to smaller branches. This again shows how the light which we call life takes a main channel for its expression, and spreads through all the different organs, the small channels or boughs.
