Our magnificent God created an incredible computer in our heads, commonly known as our brain. The brain functions with frequencies, the number of times a wave repeats itself per second. The EEG (electroencephalograph) measures bands: Gamma; greater than 30 Hz; Beta; 13-30 Hz; Alpha; 8-12 Hz; Theta; 4-8 Hz; and Delta; less than 4 Hz. A quick thumb nail sketch of these frequencies would be:
Delta- deep sleep, unconscious mind, and an empathy state; state of trance.
Theta- subconscious, daydreaming, fantasy, anxiety, could be state of inhibition.
Alpha- bridges conscious and unconscious, relaxing, alert, integration, balance.
Beta- normal rhythm for problem solving, judgment, decision making, processing.
Gamma- multi-tasking, high task processing, memory recall, math, concentration.

There are several good studies on the movement and use of these stages, and the shifting from one to another, and of usage of all of them together. (see http://www.brain.web.com – by adding some appendages gives a fuller picture, /science.htm; /gamma 40 Hz, for Binaural Beats.)

I mention these because of the great amount of information that explains the whole concept. When speaking of shifting, one can relate to the shifting of a manual shift on an automobile. However, when one shifts from one to four, or from four to one without a clutch, there is a problem. This is what happens to our minds when misused by enhanced mind control. (refer to Rom 1:31, 32; 1 Cor 2:14)

Watching television for a period of time puts the mind in an Alpha mode, while playing a video game (extreme violence) will exercise a Gamma mode but put the consciousness as low Theta. What this means is that a mind loses its ability to rationalize, especially morality. Other constant foreign concentration such as competitive sports, amusement parks, and games requiring intense concentration block inhibitions and traditional rational thinking. In church, the Pentecostal worship settings, eagerly promoted by Vatican 2, such as clapping , dancing, clowns, theatrics, speaking in tongues, (gibberish) and very loud “Christian rap and praise music,” which is invading every denomination, cause the brainwaves to be so contorted as to disregard the gospel and impair the teachings of Scripture with trauma based conditioning.

When a TV becomes the babysitter of an infant, and the video game for the adolescence, the brainwaves cause stress, and virtual reality to the point that pharmaceuticals are prescribed, or a restless, anxious child is born. Living in a stressful state creates a condition of pushing a camel through a needle, and along with an animal based, refined food and sugar diet, can create havoc in any life. The frequency cadence of TV alone, the flickering rate/second, (HD and flat screen can be 60 Hz) the music stimulants, and deep base sounds are insidious, mind altering to a condition of slavery, likened to Meth/Speed, which is mind altering and mind control. The appetite for continuous indulgence is as strong as drug abuse, alcoholism or pornography.

The solution is found in reading and absorbing Scripture, nature, a strong biblical family base, and a heart-felt relationship with Jesus. (refer to http://en.wikipedia.org/wiki/Endorphins)
