The tree is a symbol for intense inner life and development. It symbolises a link between the physical world and the spiritual world. It stands as a metaphor for our human bodies with the branches of the tree reaching heavenward just as our minds reach for higher realms of consciousness in our search for wisdom. The roots of a tree are set firmly in the physical world as are our own feet placed upon the same earth. The trunk of the tree and the spine of the human body connect the two realms.
