Introduction
The Mind
Filled with confusion
Who is its' guide?
Make it
A sharp point
A smooth lake
A gentle breeze
A mountains' root.
-Bu Zhen Tsu
Have you ever gone to a party and thought about work the whole time?
Or thought about the evening too much at work?
Or carried on an internal dialogue when you should have been listening to what your lover
was trying to tell you?
Have you ever wished that you could just "change your mind" but have been unable to do it?
By learning the sensations associated with specific brainwave states, you can learn to enter
and leave mental states of concentration, relaxed attentiveness, or deep relaxation.
Using the WaveRider can help you to gain this sense of awareness. Through repeated
practice, you will learn what you need to do to enter into and switch between mental states in
real life situations.
One way to think of the brainwave frequency spectrum is as a continuum of arousal. The
delta waves of deep sleep are on one end, the high frequency beta waves associated with an
active mind are on the other end. The alpha peak or dominant alpha frequency is a key point
in this continuum. Frequencies above it, (Beta, SMR) tend to stimulate arousal. Frequencies
below it (Theta, Delta), tend to decrease arousal. It is thought by some, that alpha represents
an idling state, which portions of the brain return to after either completing or tiring of a task.
The alpha peak varies between individuals and changes with age. It tends to go up until the
early twenties, then levels off until the the forties or fifties. It then decreases with old age
gradually getting down into the Theta range. There is some speculation that this may be the
reason for resurfacing of childhood memories as we age. It has also been observed that the
alpha peak tends to downshift with the length of time one meditates.
Peak performance is a choice of the appropriate brainwave state. Producing the appropriate
mental state for each situation: working at your job, playing at your sport, being on vacation,
