As we come to understand that all things come from the formlessness of Source consciousness, we come to the inquiry of how that Divine Intelligence manifests itself in the material plane.
In this context, all aspects of the material plane are connected through the roots and branches of the World Tree, acting as the medium of transmission for the Divine intelligence that sits behind all things. In this way, the World Tree is the neural network of that intelligence, with our individual selves being expressions of that much larger thing.
The self as the Tree
The Nervous System of Gaia
In this way, our individual selves and the network of our nervous system is a scale model of the much larger network of the World Tree, paralleling the Divine form which exists on all levels of reality.
Simply put, we are the Tree, and the Tree is us, all expressions of the same underlying pattern.
