Answer:
To understand psychosomatic disorders we must know the mechanism called competitive blockade.
1. Competitive blockade:
If two thoughts enter the conscious mind at precisely the same time it leads to blanking of mind and abolition of all movements, emotions, feelings and thoughts. This results in,
1. False peace
2. False self-control
This is the easiest way of getting peace and also of controlling our body and mind, though both are false.
2. Requirements for competitive blockade:
1. Unified Negative Emotion, which is made by merger of many or thoughts of all of our problems
2. Blocking thought - in this case some physical disease for example knee pain.
3. Voluntary force
4. Unwanted part of mind.
3. Effortless cure for two problems!
When ever the Unified Negative Emotion tries to enter the conscious mind we can block this with the thought of feeling of mild joint pain we have. The blockade not only makes the Unified Negative Emotion innocuous but it also relieves the joint pain.
4. Creation of Psychosomatic disorder:
If the voluntary force is depleted then there would be crossing over of emotions. Thus, the mild joint pain starts producing extreme discomfort. However, all of our mental problems vanish without a trace. The discomfort is worth having because unlike our mental problems we can reveal it to all.
X-ray, MRI, etc will not reveal any abnormality and the pain will not respond to drugs that were previously effective. Even new and powerful drugs may be ineffective.
Thus, Psychosomatic disorders are caused by failed competitive blockade.
