The fourth meaning of spirit is the source and the goal of all things, something towards which all are bound, to which all will return. It is that spirit which in religion is called God. And the best way of explaining this meaning of spirit is that it is like the sun, the center of all life, the divine spark in us. But the sun is not as small as it appears to be. Then what is the sun? The sun is all. The part of the sun that we recognize as the sun is the center of it, but the sun is in reality as large as its light reaches. The real sun is light itself. But as there is a point which is the central focus of light, we call that point the sun.
