The Water,
Circle, and
Power Principles
Can Lead
Any Martial Artist to Victory!
By Steve
Petermann
Out of the
corner of my
eye, in the
reflection of
the mirror, I
saw Rudy grab
the bamboo
training sword.
As a lower belt,
he had no reason
to pick it up,
and since only
he and I were in
the training
hall...
Turning as he
swung, I slid
in, enveloping
him and the
sword, wrapping
my arms around
his. Using his
energy from his
missed swing and
adding a little
of my own
derived from
twisting my
hips, I
redirected his
power and sent
him tumbling
across the mat.
As he came to
rest, Rudy's
mischievous
smile turned
into one of
incredulity. I
stood there
amazed. "Wow,
this stuff
works!" We said
at the same
time.
Fortunately, I
had seen Rudy
smile during the
swing.
Unfortunately, I
saw it too late
to stop his wild
ride. He
admitted that he
had intended to
give me a
surprise whack
with the
practice sword.
Neither he nor I
knew that his
prank would lead
to our deeper
understanding of
the principles
of hapkido.
A Matter of
Principle
Hapkido is a Korean martial art whose name means, "way of coordinated
power." It
includes more
than 3,500
self-defense
techniques -a
veritable
mountain of
moves to
memorize.
Consider this:
Even if you were
to practice 100
techniques a
day, you would
still have 400
to go at the end
of even the
longest month.
Only by focusing
on the
principles of
the art can you
practice the
techniques
efficiently and
effectively.
Hapkido is
composed of
three main
principles, the
water principle,
the circle
principle, and
the power
principle.
Although not
every technique
exhibits all
three, all
techniques uses
at least one.
The Water
Principle

Water has many properties that can influence the way you act and react.
By imitating
it's yielding
nature, you can
improve your
evasion and
envelopment
skills. If you
yield to your
opponents
attack, you will
sustain little
or no damage
should he strike
you. In a game
of tug of war in
which power
opposes power,
the strongest
person will win.
However, if one
side let's go
unexpectedly,
the other one
will tumble into
a heap.
Likewise, when
your opponent
pulls or pushes
in a fight, the
best option may
be to simply
yield.
Yielding,
however, does
not just mean
"letting go" or
"backing off"
-although they
are components
of the concept.
Successfully
yielding for the
purpose of
evasion and/or
envelopment it
enables you to
avoid the
opponent's
attack and pulls
you in position
to respond
effectively.
A distinctly
different
property of
water is it's
ability to
overwhelm. That
is illustrated
by the force
exerted against
your abdomen
when you do a
belly flop into
a swimming pool.
The ability to
overwhelm is
important
because the goal
of self-defense
is not so much
to avoid a
single blow as
it is to
neutralize the
threat. When you
apply force to
neutralize a
threat, your
action should
have a
psychological
and a physical
impact on your
attacker. In
other words, it
should overwhelm
him. That will
minimize the
amount of
physical injury
required to
convince him to
desist, and will
expose you to
less danger than
in a traditional
give-and-take
encounters.
Water also
embodies the
quality of
persistence. If
you train hard
in any art and
still believe
you are not
improving, you
should recall
the persistence
of water.
Although the
change it
effects on stone
may appear
agonizingly
slow, the
results are
dramatic. Just
as a continuous
drip will bore a
hole into the
hardest stone,
continuous
practice will
eventually
penetrate even
the hardest
head.
The Circle
Principle

The properties of the circle and the way objects move along a circular
path can help
you expect the
unexpected and
develop
smoothness of
motion. They can
also teach you
how to generate
power without
resorting to
lateral or
vertical
movement, which
is important
when you
overcome your
opponent's
resisting body.
The distance
traveled by an
object with a
short rotational
radius is less
than the
distance
traveled by an
object with a
longer
rotational
radius.
Therefore, the
circle principle
teaches you to
redirect a
straight punch
or kick into an
arc, thus
off-balancing
the opponent. By
turning yourself
(the hub of the
wheel) as
quickly as
possible, you
force him to try
to run around
the arc traced
by your arms or
legs (the end of
the spokes of
the wheel). When
he fails to do
that, he falls.
When the
opponent falls,
he does not
continue in an
arc; rather, he
takes off in a
straight line
away from the
impact site.
This property of
circular power
that redirects a
force tangential
to the arc can
help you
defensively,
too, by reducing
the effect of
blows you cannot
avoid. When an
opponent's
strike lands on
you and you are
rotating, the
force will be
spread over a
wider area and
part of it will
be cast off.
The Power
Principle
In the beginning of your training, you may think ki (internal energy)
refers to only
your own power.
Later you learn
that it also
includes your
opponent's power
and later still
you will
discover that it
includes the
world's power.
Hapkido deals
with the
application of
all those powers
in terms of
inertia. Power
has the property
of facilitating
motion. Inertia,
however, exists
in both moving
and resting
bodies.
Power as
described by the
power principle
is not strength.
If the strength
of your body
were the sole
determination of
self-defense
ability, all
training would
revolve around
building muscle.
However, smaller
and weaker
people who learn
the power
principle can
avoid or
redirect an
opponent's power
and successfully
defend
themselves.
To harm you, an
opponent must
exert energy.
His exertion
tires him, and
directly
resisting his
efforts tires
you. However,
when you
minimize your
expenditure of
energy and
attempt to use
the energy
expanded by your
opponent, you
gain maximum
effect with
minimum efforts.
In this way, you
can outlast your
opponent if
necessary, and
you can more
easily overcome
differences in
height and
weight. Once you
learn the power
principle, you
will never fight
alone; you will
always have your
opponent helping
you.
Combining
Principles
By combining two or more hapkido principles, you can achieve great
things. For
example, using
the circle
principle in
combination with
the power
principle, you
can encourage
your attacker to
move quickly in
one direction.
Uncontrolled
inertia may
cause him to
topple, but if
you change
direction, the
original inertia
will be
amplified by the
change and the
application of
the opposing
energy. When
that combination
is used against
a joint or to
increase the
damage of a
blow, the result
can be
overwhelming.
The application
of the three
principles can
extend beyond
the realm of
self-defense and
into your
personal life.
When you study
hapkido, you
embark on a
course that will
hopefully put
you in harmony
with yourself,
with the world
around you and
even with your
attacker. You
will strive to
be like a large
body of water
-calm on the
surface but with
sufficient depth
for love and
knowledge. By
adopting the
properties of a
spinning circle,
you can deflect
personal attacks
and failures and
stay focused on
completing all
that you begin.
