The word power is an interesting one, possessing many definitions (over 30) spanning precise meanings in physics to the metaphysical. In the world of being, the word power is often collapsed with the idea or meaning of force. Yet really force is what is present when power is not. Power is effortless, achieving intentions without force or struggle.
The same thing arises in the martial arts. One can be very forceful, but true power comes much as the old Chinese saying “one pound moves a thousand pounds.” The soft power of an Iron Palm break, or of a tai chi practitioner’s strike or push, both examples of this.
It’s no wonder to me (and I find it very interesting) that many of the great masters of old are remembered as being wise and calm, and why there are great stories of masters from such places as Mt Wudang or Mt Song and the Shaolin Temple. When you put those two together, or when one leads to the discovery of the other, well, it just seems natural what would arise inside that: Effortless Power in both realms.
