Expanding upon the concept of a core point two inches below the navel, there is
a core line that extends from the inner arches of the feet all the way up the
body, through the deep front muscles up the neck and ultimately into the center
of head and then fountaining out the top.
Optimal posture, in standing, sitting, and movement, involves a flow through
these core muscles so that there is no impingement of muscles creating pain in
motion around a joint. This involves proper alignment of the body so that
gravity doesn't compress the joints more than they are meant to be.
The definition of an instantaneous axis of rotation, according to [a website that no longer exists], is "the ability for any joint complex in the human body
to function without internal derangement during normal human
activities...Normal neuro-mechanical function allows pain-free motion about a
Basically, we want freedom and full range of motion around each joint, and this
involves keeping a sense of the core line and allowing the extremities to move
freely, but integrated, around it.
or navel point, is located in the lower abdomen two inches below the belly
button. It is supposedly the center of gravity, from which all movement and
In Pilates and yoga both the navel point is crucial; it's where that nebulous
"core" or "powerhouse" is located. When in Pilates classes
you're told to bring your navel towards your spine, you're creating a
"container" of sorts--you're activating the lumbar multifidus, the
deep spinal muscles under the erectors, and the transversus abdominus, the deep
abdominal muscles under the "six-pack" rectus abdominus. Those two
vertical muscles sandwich the core, and the horizontal "lids" of the
container--the respiratory diaphragm and pelvic floor--give the core the
potential for dynamic movement. That container allows free movement of the
extrinsic muscles around the body at the same time as building up, springlike,
power for movement.
In yoga, the navel point is referenced when bandhas, or yogic locks, are
spoken of. Pulling up the rectum and genital muscles is the first, or root
lock; pulling the navel point towards the spine activates the second, diaphragm
lock. Activating the second lock will automatically activate the first. The
third lock is at the neck; it involves straightening the neck by bringing the
sternum slightly up towards the chin (another important Pilates move--during
the all-important "Pilates hundred" as well as other abdominal
exercises, it's encouraged to lock the chin as if holding an egg underneath
Basically, when you activate those three locks in yoga or Pilates, you're
creating a bunch of horizontal "lids" as well as solidifying the
sides to the container by using those deep core muscles. When the body is
stabilized in this way, it's like you create a super-solid grounding within
yourself--you give your center a context, a definition, and from there you can
have infinite power and outward expansion. Plus, having a physical sense of
core here also forces energy to come up the spinal pathway, freeing up all
sorts of blockages and, in yogic theory, opening a person up for spiritual
In kundalini yoga, it's said that when you move and speak from the navel point,
you can be 100% behind an action or statement. The navel point is the place
around which your fetus shaped itself--the center of your physical orbit, and
where, if you re-connect there, you remember yourself. A strong navel point
will create an open heart center, so moving from there comes first.
operates under the laws of physics--that of gravity and momentum, inertia,
Seems pretty obvious, but we forget sometimes that gravity is the single
largest external contributing factor to pain in the body. Misaligned parts
cause shortness in compensating muscles and an equal and opposite set of
over-stretched muscles corresponding.
It's said that in this particular age of humans, the evolutionary contribution
we are making is the development of the rational mind, the faculty of critical
thinking and creative intellectualism. That said, many people have difficulty
staying in the body as all their focus goes into their heads. If you look
around, particularly at people who spend a lot of time thinking, you'll see it
in their physical bodies--heads that are held fixed still and thrust in front
of the upper body. The rest of the body, borne down by the subconscious
compensations necessary to remain upright in gravity, adjusts accordingly--one
pattern might be that the chest sinks, bringing the heart into a subordinate
position to the head, the shoulders come forward to balance out the hump in the
upper back, the stomach pooches forward, and the legs hyperextend.
Other patterns are possible, depending on the psychological makeup of the
person and/or other factors both internal and external. The point is, gravity
will assure a global effect of any imbalance in structure or function in the
body. It makes us accountable.
The tendency of the head to dominate is one of the reasons why yoga emphasizes
so much the lifting of the heart, the leading of the heart in motion, at the
same time as the belly (identity) is stabilized. This puts the head
automatically in its rightful position--as active and alive, receptive of vital
energy from below it, but ultimately as an instrument--where thoughts serve the
person, but are not ends in themselves.
allowing the breath to do the work when we move...
We pay so little attention to the breath, but it's the interface between our
inner and outer worlds, and thus it shapes the form we inhabit, the effect of
that interface. The inhale demonstrates our reaching out into the world,
pulling in life and owning our vitality--it's why it's called
"inspiration." The exhale shows our ability to let go and ground,
allowing the universe to hold us.
One interesting exercise I remember from my Rolfing training was walking around
the room, and first imagining that our insides were completely water, then
letting that go, and imagining that instead we were walking around and the
environment was completely water. Those of us who preferred inhaling liked the
first scenario better; those of us who liked the exhale better felt more
comfortable walking around in water.
It's not really relevant here
why people prefer one or the other (there's some long explanations about
cranial waves in flexion or extension preference, but it could just be karma or
astrology). Inhale-people tend to have ribs that are more lifted in the front,
and more barrel-like looking at them from the side. Exhale-people have ribs
that are more depressed in the front, and flatter looking at them from the
side. This is connected with mood as well--inhale people breathe more into the
chest and tend to be more upbeat but less grounded, and exhale people are more
belly-breathers and tend towards depression or self-absorption.
These are tendencies that will often dominate when we are not conscious of
breath. Our fears and our patterns will direct and maintain our posture. When
we are conscious of breath and begin to allow it to unfold and lead us, rather
than remaining an effect of fear of looking within (inhale people) or looking
without (exhale-people), our attention turns that fear into a challenge to
stretch beyond, a place to find joy and creativity and expansion.
Here's my reasoning. I am an exhale-person, with depressed ribs that look very
flat from the side. I adore exhaling and can breathe out forever, and when I'm
not aware of it my tendency will be to sink down into my exhales and barely
breathe in at all. However, when I start looking at this pattern and saying
hello to my breath, then my inhales become intriguing, and as I explore
expanding my ribs the glorious stretch to intercostal muscles rarely used
becomes a place of bliss--a place where I haven't been aware that I can grow my
universe. It just feels good, it feels like a stretch that I don't get on the
exhale. And that goes both literally and figuratively.
So--we let the breath do the work when we move, in yoga or in daily life. And
when we start paying attention to the breath and allowing it to lead us, it's
like giving control over to the soul rather than the ego and
personality--letting spirit guide us rather than the instrument, going beyond
our fears and defense mechanisms and transcending the perpetuation of patterns.
This BBC article basically talks
about how research shows that activity in the frontal brain in areas where
emotions are controlled increases in women during PMS. It's suggested that
because of surging hormones, the brain attempts to increase emotional control,
and women who experience PMS-driven irritability and outbursts of anger lose
this control by not having enough activity in this frontal brain area.
and his anthroposophical medicine might have some pretty cool things to say
about why some women would experience not enough frontal brain activity to
control the increased emotions and some would have enough. Basically, he talks
about how the body has two poles--an upper, cephalad, pole, and a lower
digestive-metabolic pole. The relationship between these two poles is regulated
by a rhythmic system. When there's stress in the system, and particularly in
the reproductive organs or digestive area (lower pole), what happens is that
food coming into the body isn't adequately stripped of its foreign matter, a
necessary step occuring at the cephalad pole that prepares the food for
infusion at the metabolic-digestive end with a vibration that the body will
find digestible. So the result is that energy from the cephalad pole will be
pulled down to finish the job, and the result can be migraines or other
difficulties in the head--hence the connection between migraines and
We could also draw the conclusion that the same thing happens in the case of
PMS--stress in the reproductive system draws energy down and the cephalad pole
doesn't have enough juice to control the emotions.
I've read somewhere, I think probably in Christiane Northrup's writings, that
the emotions that come up during PMS are honest releases of stuff that's
repressed--so even if one seems crazed, that's stuff that needed to come out
and can be taken as communication to the mind by the body. I am thinking that
this emotional repression, which occurs in the second chakra (located below the
navel, this energy center controls emotion) is the stress that causes this
whole cycle to begin--bringing the cephalad energy down and creating loss of
control so there is SOME way for the body to release the pent-up emotion. Oh,
body wisdom, it's so lovely!
The answer, of course, is to express emotion! Go punch a pillow today!
