Power is the culmination of several principles -- the sum total
of which maximizes one's expenditure of energy. To obtain it, one must
add all ingredients associated with economy of motion (proper body
alignment, the following of direct angles and paths, etc.) so as to
enhance speed. You must also add a mixture of torque (rotating force),
body momentum (horizontal momentum through the use of shuffles; and
diagonal or vertical momentum utilizing gravitational marriage), and
deliver your strike and all movements from their point of origin.
Every action must be simultaneously coordinated to bring about focus
at the exact moment of contact.
It has been stated that when mass is coupled with velocity power
increases proportionately. While this may be true, we should examine
the term mass as it relates to power. Many refer to the mass of a
natural weapon used to strike a selected target. In fact, it is the
general consensus of Martial Artists that the mass of the natural
weapon employed is what creates power at the time of target impact.
While this statement may be true in part, it is not the total answer.
As explained in Volume IV, POWER is the magnification of force aided
by concentrated focus. Its capacity is proportionate to the physical
strength, force, or energy exerted, in addition to the speed rendered.
Focus is the concentration of mind, body, breath and strength
culminating at the exact instant while blocking or striking a specific
target. What does all of this mean? Is it the mass of the natural
weapon as it strikes the target that creates the force needed to
increase power, or is it the entire mass of the body in
synchronization with the natural weapon that maximizes power? The
answer is obvious, the entire body must be in focus with the target in
order to fully utilize mass. Yes, the mass of the natural weapon does
start off independent of body mass, but at a given point, all
culminate upon impact. Therefore, it is not only the mass of the
natural weapon, but the added mass of your body that synchronizes at
the point of contact. Mass takes in the entire body and not just a
portion of it.
