open focus
(widened or
diffuse attention), you can reverse the strains of stress. Open focus
shifts your brain away from an emergency state that is characterized
by a narrow focus. When he and other researchers used electroen-
cephalograph (EEG) instruments to measure brain - wave activity,
they discovered that particular patterns represent specifi c states
of mind. When you shift to an open focus, your brain ’ s electrical
activity drops to more relaxed lower frequencies. During an open -
focus state, the sympathetic part of your autonomic nervous system,
which engages the fi ght - or - fl ight response, tones down, and the
parasympathetic system increases its dominance. This means that
by practicing open focus you activate your parasympathetic nervous
system and a more relaxed state of mind.
Open - focus attention increases the effi ciency of large groups of
neurons that fi re together. When these groups include neurons that

fi re for extended periods in synchrony, there is a greater potential to
enhance your mental health. The term
phase synchrony
means that
many parts of the brain are producing alpha waves, which are asso-
ciated with a state of wakeful relaxation, and that these brain waves
are rising and falling in unison (Fehmi and Robbins, 2007). This
means that large numbers of neurons are fi ring together to produce
powerful types of focused brain activity.
When you produce high - frequency, nonsynchronous beta-wave
(associated with normal waking consciousness) activity, it ’ s like the
chatter of many people at a party having separate conversations. In
contrast, synchronized lower - frequency brain waves are like every-
one at the party singing together. It is like the fourth movement of
Beethoven ’ s Ninth Symphony: the chorus is magnifi cent and the
experience is transcendent.
Parasympathetic Meditation
The antithesis of the fi ght - or - fl ight response is the relaxation
response, which is the body ’ s way of calming itself down. The relax-
ation response involves activating the parasympathetic nervous
system, which promotes a slower heart rate and a slower breathing
rate, whereas the fi ght - or - fl ight response is activated by the sympa-
thetic nervous system.
During the last few thousand years, people in societies through-
out the world have developed techniques to induce the relaxation
response. They activated the parasympathetic nervous system with-
out knowing of its existence. Various techniques were developed to
cultivate a state of calmness and stillness. The increased feelings of
tranquility gave them a sense of peace and unity with their environ-
ment. The techniques used to gain these experiences are prayer and
meditation, which are facilitated by an open focus and by widened
attention.
The parasympathetic nervous system can also be activated by the
more recently developed methods of self - hypnosis, visual imagery,
and relaxation techniques. When I was trained in hypnotherapy in

the early 1980s, I noticed signifi cant similarities with the meditation
practices that I had learned in the early 1970s. All these methods
promote relaxation and a sense of inner peace. Although the names
and methods are different, they involve the same principles of wid-
ened attention and the same brain physiology, which I ’ ll describe
later in this chapter.
Too often we look for special differences and want to believe that
our own method is more powerful, sacred, or pure than the others.
Although researchers have examined one technique at time, these
studies reveal many common denominators.
The methods of hypnosis, prayer, meditation, visual imagery, and
relaxation all involve widened attention and the letting go of sym-
pathetic nervous system arousal while doing things to activate the
parasympathetic nervous system. The fi rst step of each method is
to focus on breathing, which serves many purposes. By breathing
abdominally, you can shift from your sympathetic to your parasym-
pathetic nervous system. This slows your heart rate, which calms
you, and activates neurochemical systems that calm your amygdala.
By focusing on breathing, you can also clear out the nervous chatter
of worries from your mind.
Meditation combined with yoga promotes physiological as well as
mental calming. Since a considerable amount of energy is wasted in
maintaining muscle tension when you suffer from stress, you may
feel all wound up and thus fatigued. When chronic stress builds up
in the muscles, it makes the tendons thicken and shorten due to
overdevelopment of the connective tissue. Stress contributes to the
overactivity of the sympathetic nervous system, which results in a
buildup of tension in an already taxed nervous system. A quick way
to get rid of the buildup of tension and activate the parasympathetic
nervous system is to stretch and breathe deeply.
The brain requires a steady fl ow of blood, and since the muscles
are endowed with a rich blood supply, stretching can facilitate a
healthy blood fl ow to the brain. Stretching, like exercise, promotes
an energized capacity to focus combined with a feeling of relax-
ation. By stretching your muscles, you force or pump the used and
deoxygenated blood back into your heart and lungs for refueling.

This results in the replenishment of your brain with reoxygenated
blood. Stretching therefore promotes a refreshed brain, invigorates
the muscles, and releases built - up tension.
Combining the practices used by yogis for a few thousand years
with simple stretching synthesizes many techniques and can be
called
hybrid yoga.
Hybrid yoga does not have to be a complicated
routine that you engage in only when you have set aside a block of
time. You can take a moment, even when you ’ re at work, to slow
your heart rate by breathing deeply, stretching, and focusing your
attention on how your muscles feel as they are stretched. Try to
visualize relaxing your muscles so they won ’ t constrict your blood
from fl owing back to your heart for reoxygenation. After visualizing
your heart revitalizing your blood, imagine how that blood fl ows
to your brain and brings nutrients that make your brain both more
relaxed and more alert.
You can do all of this in just two to fi ve minutes. When you
return to whatever task you had been trying to accomplish, you ’ ll
fi nd that you ’ ve rid yourself of built - up stress and that you ’ re able to
engage in the task at hand with renewed vigor and a calm sense of
alertness.
For example, let ’ s say you ’ re at work in your offi ce cubicle or you ’ re
in the break room and you have only about fi ve minutes to practice
a little hybrid yoga. Stand with your feet separated by approximately
thirty inches. Bend over and stretch your arms toward your toes. If
you can touch your toes, fi ne. If not, don ’ t worry about it. Feel your
muscles stretch and the blood fl ow downward. Gradually stand up
straight and raise your arms outward and upward, making a
V
and
inhaling deeply to fi ll your lungs to capacity. As you are standing
completely straight with your arms extended upward, hold your
breath for ten seconds, then let your arms slowly drop while con-
tinuing to keep them extended. Exhale deeply and let out more air
than you think you have to exhale. Once your arms have dropped to
form an inverted
V
, repeat the entire process.
There are seven general principles to follow to activate your
parasympathetic nervous system. These principles make up hybrid
yoga (but are common to prayer, meditation, relaxation exercises,

. Think of these principles as a way to refresh your brain
and feel more calm, focused, and energized. The seven principles
of parasympathetic meditation are as follows:
