"As you get older, your muscles weaken, and you can no longer lift and pull. In the end there's a limit to physical strength, no matter how you build it up.
That is why Ueshiba Sensei says that unlimited power comes from breath power. In effect, it is based on natural principles. If the other person comes powerfully against you, and you respond by simply taking his power into yourself, there is no need for any effort."
-Gozo Shioda
