INTRODUCTION
Theta Waves : (4-7 per second): Slow, Low voltage waves, predominant during drowsiness.
Delta Waves : (0-3 per Second): Slowest waves, high voltage- recorded in deep sleep.
Many investigation 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 psychophysiological experiment, made in San Francisco, California (U.S.A.) at Langley Porter Psychiatric Institution.
These included Zen, Tibetan, Tantric and Raja Yoga Meditation, taught by Brahma Kumaris World Spiritual University.
Most of the Meditators showed Alpha or Theta waves when hey meditated. These waves are replaced by non-coherent Beta Waves when they stopped meditating.
The results were remarkably different in the individuals, practising Raja Yoga Meditation. It was Delta Waves usually not longer than 50 micro volts, even while awake and solving problems. Normally, Delta Waves are not produced except by a person in the deepest state of sleep.
By subtracting eye movements from the graph, it was determined that the wave-pattern was not produced due to movements of the eyes. OTher double checks were also made. No sign of brain abnormality was present either.
In simple terms, through Raja Yoga, one learns how to detach the mind from its physical engagements 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 centered in his soul, not in his brain, continues to function at peak levels. The difference between conscious apparatus of a Raj Yogi and that of ordinary people is that due to the high level of detachement, his cortex is no longer being 'driven' by sensory input and conditioned physical thought-response patterns. His mind, in a state of liberation from physical attachement, allows the cortex to remainin its inherent Delta rhythm.
The above conclusion is supported by other experimental evidence as well. For example, when the brans of animals are cut (with the animals alive and conscios) so the cortex is isolated from the central region of the brain, Delta waves are produced. A Raj Yogi simply cuts the connection intellectually through re-rerouting his mental energy rather than through a physical operation.
The system of Raj Yoga Meditation has now been so well analysed and clarified by Yogic researches at the Brahma Kumaris Spiritual University the beginners 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 correlatives of such a brain-wave production are serenity, self-confidence and supersensous joy.
People today are very much aware of their Physical as well as Psychological Health. First of all i want to tell you that There is no medicine greater then faith, in other words we can say - "Vishvas he sabse badi dava hai" if you are taking a medicine with full faith and beliefe (i am not asking about not allopathic / pharmaceuticals), it act vary fast.
Various means have been suggested as keys to improving one's well-being, but the fact of psychological stability is still too often downplayed, either because its importance is not fully recognized or because no way of strengthening that stability has been known.
Numerous scientific investigations have undoubtedly proved that psychological stress can have disastrous effect on the physical health. In diseases like hypertension, diabetes, peptic ulcers and bronchial Asthma, psychological stress is one of the factors for causing or complicating the disease process and also disturbs the recovery with pharmacological treatment. Neverthe-less, the knowledge of harmful effect alone does not help us much to lead a life free of worries, stress and tension. More significantly, there is evidence that a simple means exists which relieves stress and re-establishes mental harmony when practised regularly, and is thus a vital adjunct to any programme for maintaining and promoting health. That means is known popularly as Raja Yoga Meditation.
PSYCHO PHYSIOLOGY OF RAJA YOGA
In 1791, Galvani was the first person to declare that nerves contain some intrinsic form of electricity. Since then there has been a great interest in measuring the electrical activity of the brain. Hans Berger made the first recording of electroencephalogram (EEG) in 1925. EEG is the measurement of rhythms of electrical activity originating in the brain.
Biofeedback means sending back of biological information to the person whose body is producing the information. This study, research and application have blossomed only in the 30 years.
TYPES OF BRAIN WAVES
There are Four Types of Brain waves : which we produce in different states of alertness :
Alpha Waves : (it is 8-13 per second): Moderately fast, High in Voltage, recorded when an individual is awake, eyes closed and is in relaxed nonattentive state.
Beta Waves : (More than 13 per second): Comparatively faster, low voltage waves recorded when an individual is awake, eyes open, and is in an active or attentive state.
Theta Waves : (4-7 per second): Slow, Low voltage waves, predominant during drowsiness.
Delta Waves : (0-3 per Second): Slowest waves, high voltage- recorded in deep sleep.
These included Zen, Tibetan, Tantric and Raja Yoga Meditation, taught by Brahma Kumaris World Spiritual University.
