As you can see, it has a lot to do with trees, specially oak trees. The word matter is derived from the Latin word materia, which itself is derived from Mater, which means mother.
Materia initially refers to the trunk of a tree. Lightning striking a tree is symbolic of life coming into the material body, and trees grow from the mother, depending on rain from the sky, the father.
You're the tree, the son of the sky father and the earth mother and all of our roots are interconnected.
