energy and particles. atoms and molecules. protons, neutrons, electrons. movable. maneuverable. subject to change under stress. hands digging into a 2 x 4. distort its shape. finger tips separating splinters. rectangles divide. cells dissect. blood. 

matter effecting matter. thats all there is, ever. 

the seed that grows the tree. the ax that wrecks the forrest. there is no difference.
