Hello Will2002, this is the description that I found at
www.centerpointe.com for the different mind states:
The human brain operates neuro-electrically. Brain activity appears as a series of micro-voltage firings between neurons (brain cells), or more precisely, through networks of neurons. With the use of an electroencephalograph machine (EEG) these firings or pulses can be detected and measured. These neuro-electrical impulses are categorized in terms of a frequency range of four major brainwave patterns (Hz = Hertz = cycles/pulses per second):
- Beta (13-30+Hz) Beta is the state of normal, wakeful consciousness. As we are working, driving, talking, etc., we are likely in Beta. On the higher extremes, Beta is sometimes associated with anxiety, panic or stress.
- Alpha (8-12.9 Hz) Alpha is a state of light relaxation. Not a sleep state, but usually reflective of a calm, focused mind. Alpha is sometimes called the "superlearning state" because the brain seems to be more receptive and open to new information. Alpha is also considered ideal for creative brain storming. Most meditation occurs in this state.
- Theta (4-7.9 Hz) Theta is a state of deep relaxation. Sometimes a sleep state, sometimes not, theta reflects a state of dreamlike awareness. Dreams and a deep, meditative state of consciousness are common characteristics of theta.
- Delta (0.1-3.9 Hz) Delta, the deepest of the brainwave patterns, is a state of deep sleep, or trance-like consciousness. Maintaining awareness into delta can result in opening access to the unconscious portion of our consciousness.
The only way to be certain that you're in the Alpha state is with an EEG machine; however most people describe it as a relaxed, flowing state. There were numerous discussions on achieving the Alpha state here so a search should give some ideas.
