meditation is a very prestigious word included in yoga. In sanskrit, it is called dhyana or samadhi. Dhyana is a state of concentration of mind on one stage object so that same experience arises concentration in the mind again and again without they’re being any other experience that may intensive.

In this state there is consciousness of three things

	The object
	The experience, and
	The one who experiences ,or the “I”

When the consciousness of the “’I’ is silenced there remains only the experience of the object. This what happen in the state of samadhi. All these stages come under meditation. You can practice meditation to attain the state of samadhi in several ways. Some of common ways are reciting words (mantra),by chanting Aum, by using a material symbol like a phallus (shivalinga) or an idol picture or the flame of lamp.

The most important aspect in each of these methods is to stop the process of desire (trishna). Unless you are able to stop the desire, your mind cannot become steady.

Samadhi is used to lead yoga ultimately to self -knowledge (atmajnyana),which is the culmination of yoga according to sage patanjali and also according to the ancient authorities of hatha yoga.

The highest goal is however beyond the reach of most people who practice yoga as a means to living healthier lives. But scientific researches on the state of meditation have shown clearly that physiologically many advantages are gained by the practice of meditation such as slowing of the heart ,breath and mind. This helps in prevention and cure of a wide range of stress disorders such as diabetes, high blood pressure, arthritis psoriasis, sleeplessness, indigestion, increased acids in the stomach, increased gas etc.

Yoga Therapy

Most of the people turn to Yoga only when they have some health problem for which, due to one reason or Another, medical treatment could not give satisfactory results. This is valid for many of the chronic diseases, which often can be attenuated but not cured and also for the psychosomatic ones, where the psychic factor is especially evident and which are therefore difficult to treat with the common medical methods. What can Yoga therapy offer these patients?

The approach, theoretical, towards a disease, or better, towards the person who is suffering from a disease, differs very much from the one of medical; science. The latter tries to isolate the pathogenic factor; a microorganism, a toxic substance, a metabolic disorder – and eliminate it. Of course, this principle is voluble, but it fails if the etiology is unknown. In this case the therapy must be symptom –oriented and often proves unsatisfactory. Yoga on the other hand, does not refuse the scientific explanation of a disease, but looks at it from another point of view: from the personality of the patient. If he is ill there must be a deeper reason behind it – a disease doesn't’t arise by chance. There is an imbalance, a disturbance in whole body – mind – complex, which creates a diseases conditions. The symptoms, the pathogenic factors, the name of the diseases are not the main issue – the root cause lies elsewhere.

Yoga hold that it depends on the individual himself if he is sick or healthy. The same instance, which causes the diseases condition, can also Cure it. What is called natural healing power is nothing other than that it’s nothing mystical from outside, but an inner capacity. All that is required is not to interfere with it.

Yoga Therapy tries is to re-establish the inner balance by various means working from the gross to the subtle . On the physical level it uses:

Asanas: They energize the organism; create awareness of the body and its function and stabilizes the mind.

Kriyas: These are simple hygienic procedures which support the body own cleaning mechanism and drag the attention of the mind towards the affected are.

Pranayamas: These are breathing techniques, which have very subtle influences on the whole organism.

Diet: Many diseases are directly or indirectly linked with wrong food habits. A change in diet can stimulate the whole system.

Simple Nature-cure Techniques: The elements water, air sun and simple procedures like massaging or steam installation are used as a support

The second line of therapy is the work on the mind. Mental disturbance anxieties, confection, and unsteadiness are the most important factors, which can cause a diseases condition. Therefore, various techniques have been developed to create positive mind status. Among others there are

Relaxation	:	both physical and mental.
Conditioning	:	Sitting in a meditative posture one tries to calm down and centre oneself.

Bhavanas: Contemplation on certain basic ideas like the transistorizes of all things can stimulate a change of attitude towards life.

These are some of the technical means that may be used. The technical aspect is however of minor importance compared to the primary goal: to create a conditions which can encourage the patient to give free way to his own inner forces. It he succeeds in doing so, the results can be surprising. It not, Yoga – Therapy is at its limits -it can work only together with nature, not against it.

Yoga has claimed that tension is diseases and relaxation is health. To this end the whole eightfold path of yoga is to purify the body mind complex

All over the world people the world people are discovering the magic of Yoga. But the fact that most of the people turn to Yoga only after they experience unsatisfactory results from other medical treatments. They probably do not realize that many chronic diseases and also psychosomatic diseases are difficult to cure with the common medical methods

This could be due to the approach taken by medical science. It tries to isolate the pathogenic factor a microorganism , a toxic substance and eliminate it. This is effective only if the etiology (cause/origin) disease from the personality of the patient.

Yoga believes that whether an individual is sick or healthy depends on him. The same instance, which cause the condition, can also cure it.
