The Breath and the Brain
Note: I believe this is a legitimate crosspost and will be interesting
to all involved.
I am interested in increasing my understanding of how the breath works
in different types of meditation practices. I was hoping to have some
of this demystified and tied together. The following is not an
authoritative article but mostly gibberish by me and a lot of
questions. Please read through it and comment and clarify as you see
fit. Thanks!
"DEEP" BREATH VS. SOFT BREATH
We are often told to "take a deep breath," to calm ourselves. I have
always thought this was an odd command, because for me, deep breathing
tends to be more like exercise. I have talked to lots of people with
panic disorders who tell me that deep breaths can bring on panic
attacks.
So what is meant by "deep?" Does that mean simply that we are taking
in a lot of air? Or does it also describe the *location* to which the
air is going. I find that the best way to stay calm, to reduce anxiety
has more to do with redirecting the breath than with making the breath
larger. Either the "deep calming breath" is either greatly
misunderstood, or there are major physiological differences that make
it work for some people and not others. Which is it?
Now as for the soft breath, I am not sure what you would call this in
yoga. In zazen we don't call it anything, but what occurs is that the
breathing slows to a barely imperceptible point. This is in some kind
of correlation to the steam of thoughts. As the stream slows, so does
the breath. This, I imagine is because less oxygen is required for the
brain to do it's thing. Physically we are taking in very little air,
but what we take in is directed to the hara.
In yoga, this would be either the second or third Chakra. Can
somebody clarify? The hara is located a few inches below the naval. In
Yoga, the third Chakra is AT the navel. The second chakra is the
genitals. So the hara is between these two points.
>From a yoga perspective then it could be said that zazen is a practice
centered on this particular chakra. Whatever benefits are believed to
be observed from this practice would then (in theory) be cultivated by
the Zen practitioner.
Note that zazen itself is NOT a breathing exercise. The breath is
observed and is in no way to be manipulated. When the breath is merely
observed it lessens on it's own. Manipulating the breath in any way is
a common pitfall of this type of meditation practice, and occurs often
by practitioners trying to artificially accelerate their progress.
FOCUS
Now I want to talk about the effects on the brain. The "soft breath"
occurs as mentation lessens or ceases. The two (generalized) vehicles
for this in Zen is Concentration vs. "Just sitting" (shikantaza). The
theravadan Buddhist corollaries to this are Samatha (calm) vs.
Vipassana (insight) meditation.
It helps to have some degree of concentration (samatha) built up before
doing shikantaza (or vipassana) For this post I'm going to focus on
concentration (no pun meant).
When you are developing concentration (joriki) you focus your attention
on the breath at a fixed point, which for most of us "zennies" is the
hara. At times this can be extremely difficult.
I have tried to note the various conditions under which it is easy or
difficult to concentrate. They can be psychological/karmic or
physical. Loose ends, arguments, general anxiety make it difficult to
focus. In the cycle of Buddhist practice the "remedy" could be said to
be the parts of the eightfold path concerning morality(Sila). In
general terms, practicing morality, meeting one's obligations and
generally not being a jerk in one's day to day life will keep one from
stirring up the karmic pot and make it easier to focus.
On the physical side (the point of interest for this post) I have
noticed that hydration, nutrition, physical fitness, and fatigue play a
role. Intoxicants are double edged. On one hand they hurt
concentration, but on the other hand they can provide an artificial
means to calming the mentation process, thereby making it easier to
concentrate on the breath while "shutting out" everything else. There
may be some benefits to this, depending on the intoxicant, but mainly
this serves as a form of recreation and isn't practice for developing a
meditative quality of mind that can be applied in all circumstances.
Other physical factors are fatigue, nutrition and physical fitness.
Being well rested helps. Eating too much will hurt. Exercise helps a
great deal. I have found one of the best times to practice zazen is
after running, I imagine because it oxygenates the brain among other
things.
So, observing this, I have found that deep breathing (Pranayama) , seem
to help focus. Please note again that Zazen is NOT a breathing
exercise. But by practicing exercises in conjunction with zazen,
(before) seem to help with concentration.
Samadhi in Yoga vs. Samadhi in Buddhism/Zen
I have heard the term Samadhi used in Yoga in terms of Kundalini
energy, chakras etc. This is probably the same as "chi" which is also
termed "Joriki" in Zen. Is it the same thing? In Zen terms this would
have to do with the cessation of thought, at which point the breath
would be barely perceptible.
The Heart Sutra, which is one of the key sutras quoted and recited
(sometimes daily) in Zen Buddhism, describes Samadhi "no eye, no ear,
no nose, no tongue, no body, no mind.." Is this the same experience
in Yoga? I have not "been there" so to speak but I have had some very
quiet moments.
Descriptions of Samadhi in Yoga and Zen seem to differ mainly in their
description of this state as being either a miraculous of
non-miraculous experience. In Soto Zen, especially, the experience is
"nothing special" since it is quite plainly the ceasing of everything
from the perspective of the meditator. In my opinion this language is
mainly used to keep one from attaching to their samadhi, since by all
accounts it is something pretty extraordinary and unusual.
Some final questions:
If you are a yoga person, what poses do you think best facilitate
concentration?
Does anybody do both yoga and zazen as complimentary practices?
Any recommended books that might help me understand the breath/brain
relationship?
