PSYCHO PHYSIOLOGY OF RAJYOGA
In 1791 , Galvani was the first person to declare that nevers contain some in trinsic from of electricity. Since then there has been a great interest in measuring the electrical activity of the brain. Hance Berger made the first recording of electroencephalogram (ECG) in 1925. ECG is the measurement of rhythms of electrical activity originating in the brain.
Biofeedback means sending back of biological information to the person whose body information to the person whose body is producing the information. This study ,research and application have blossomed only in the last 30 years.
There are four types of brain waves that we produce in different states of alertness :
Alpha waves (8 to 13 per second)
Moderately fast, high voltage waves, recorded when an individual I’d awake, eyes closed and is in relaxed nonattentive state,.
Beta weves (more then 13 per second)
Comparatively faster, low voltage waves recorded when an individual is awake, eyes open, and is in an active or attentive stage.
Theta waves (4 to 7 per second)
Slow low voltage waves, predominant during drowsiness.
Delta waves (0 to 3 per second)
Slowest waves, high voltage recorded in deep sleep.
Many investigations are conducted on individuals practising the different methods of yoga in order to assess their usefulness. One of the most recent studies involved a series of psychological experiment, made in San Francisco, California (USA) at the Langley porter psychiatric institutions. There included Zen, Tibetan, tantric and Rajyoga Meditation, taught by Brahma Kumari World Spiritual University.
In simple terms, through RAJYOGA, one learn how to detach the mind from it’s physical engagement with the sense – organs through the brain and nervous system. In this detached state, the body and brain are able to relax completely, while his consciousness is his Soul, not in his brain, continues to function at peak levels.
The difference between conscious apparatus of the Rajyogi and that of ordinary people is that due to the high level of detachment,his cortex is no longer being driven by sensory input and conditioned physical thought response paternt,. His mind, in a state of liberation from physical attachment, allows the cortex to remaining its inherent Delta rhythm.
The system of Rajyoga Meditation has Now been so well analysed and clarifed by Yogic research at Brahma Kumari Spiritual University that beginner today can easily learn effective technique to produce Delta or Theta waves, mixed with Alpha and also many other physiological and biochemical benefits even after only week of practice. The subjective correlative of such a brain-wave production are serenity, self-confidence and supersensous joy.
