what is meditation?

Meditation

"If you light a lamp and remove all the objects surrounding it, the lamp will still go on giving light. In the same way, if you remove all objects from your consciousness, all thoughts, all imagination, what will happen? – only consciousness will remain. That pure state of consciousness is meditation. You don’t meditate on somebody. Meditation is a state where only consciousness remains.

"When only consciousness remains without an object, that state is called meditation. I am using the word meditation in this sense.

"What you practice is not meditation in the real sense; it is only a concept. But meditation will happen on its own through this. Try to understand that what you are practicing at night, exercises involving the chakras, and in the morning, exercises involving the breath, is all a discipline, it is not meditation. Through this discipline a moment will come when the breath will seem to have disappeared. Through this discipline a moment will come when the body seems to have disappeared and thoughts have also disappeared. What will remain when everything has disappeared? That which remains is meditation. When everything has disappeared, that which is left behind is called meditation." 

You probably understand much more now how meditation works and how
you will become happier and healthier on an emotional, physical and
spiritual level.

A light state of meditation

A light state of meditation typically results in an increase in
production of mainly Alpha brainwaves. When you find yourself lost
in a daydream, staring off absent-mindedly into space, for example,
you're actually in a light state of meditation. 

Your brain has boosted up production of Alpha waves as a by product
of this state.  The brainwaves produced would likely fall somewhere
around 12Hz, perhaps a point or two higher or lower, but in the
general range of 12Hz.

10Hz is a state somewhat below that of a common daydream.

You may wonder then what the tangible differences would be between
this state, and simply losing yourself in a common daydream.  And
the differences would be many.

From a physiological standpoint, the breathing would probably
become somewhat slower and possibly a little deeper. There is a
common claim that the blood becomes more highly oxygenated, but
that is not really the case.

The blood is normally very close to its maximum state of
oxygenation when a person is breathing in the usual manner.

Even if you give someone a tank of oxygen to breath from, the
actual content of oxygen in the blood (in a normal, healthy person)
does not change all that much.  To get the blood to carry any
significantly higher oxygen levels requires pressurization in a
hyperbaric oxygen chamber.

On first learning this fact some people might be disillusioned
because they've been told meditation increases oxygen in the blood.
It doesn't, but in fact what it DOES do is much more significant. 

Meditation, and the accompanying states of consciousness and their
attendant brainwave patterns actually produce changes at the
cellular level.

This is far more significant than simply putting more oxygen in the
blood.  This is changing the body at the cellular level in such a
way that the cells of the body begin utilizing the oxygen they are
exposed to more efficiently, thus requiring less oxygen to get the
same amount of work done. 

This is part of the reason why you hear of people who have various
medical ailments finding that their conditions improve after
beginning a practice of meditation.  It is not that they are
injecting more of something into the body, but rather the body is
improving its efficiency at using the resources it already has.

So, for instance, you may hear that someone suffering from
emphysema begins to need less and less of their bottled oxygen. It
isn't because they've got more oxygen in their system.  It's
because on a cellular level their bodies begin making better use of
the available oxygen.

Or someone experiencing anxiety or panic attacks, who often feels
as if he or she is getting insufficient oxygen while breathing (a
common symptom of panic and anxiety,) will find this disturbing
sensation is alleviated once they begin a practice of meditation.

The deeper levels of meditation

There are many other changes besides breathing and oxygen that
occur during meditation. Improved functioning occurs in increasing
amounts the deeper you go in your states of consciousness.

The deeper the state of consciousness, the slower the brainwaves,
and the greater the improvement of the physical functioning of the
body, not just superficially, but clear down to the cellular level
(and perhaps even deeper than that.) 

Over time, the more deeply you descend in brainwave states, the
more significant your improvements will be and the greatest
benefits will be achieved.
