Living force and power to power they mean different things. Living force is the use of brute force no subtleties, no delicacies to get something like overthrow a jammed door, climb a mountain, climb to the top of a tree, etc. Power power is the confrontation between two beings, man with man (boxing), man with animal (bullfighting), animal with animal (the mating season) to determine who of the two prevails over the other.
