So, what if we are looking at trees and plants upside down? Or, maybe we should be looking at them upside down sometimes. I think because people see what is above ground, they mostly focus on that, I get it but hear me out. What if the roots are the true heart and life of the tree, at least in more of a spiritual sense, and we need to look upside down at how the tree really is.
What if the roots are the true center of life, and the branches and leaves are the 'roots' as we think of them now. Instead of roots reaching out to gather nutrients and water, think of the leaves and branches as roots reaching out to gather sun and carbon dioxide. The parts above ground are obviously required for the life of the tree and are a part of the living body of the tree, but it is the roots underground which are connected to everything in a way we cannot see, and may be the center of life which we cannot see.
Baby trees start growing roots first, then grow out into the open air later on. Trees shed their leaves in fall and pull their sap back to their roots, even evergreens pull their sap back to their roots.
Just a random thought.
