Many years ago, I myself used a process to heal myself from psychological wounds and pain suffered during my daily interactions of life. Then sometime around 1992, I started sharing it with people that came to me for healing.
Now, I am sharing with you all!
Yes, There were many "Ifs" in my life too!
Experience taught me that IF = Imaginary Fears.
IF gives me many A's- anxiety, aloofness, anger, aggressiveness, animosity, alcoholism.
Overdose of IF – turns one into an Intellectual Fool.
IF leads to Indecisive Functioning
I understood that IF = Intellectual Fatigue (also emotional).
I discovered that I was extremely deficient in control over my thoughts. By this I mean, that I could not cease to think about worrying topics at times when no action can be taken in regard to them. I understood that nothing can be as exhausting as "Indecision" and worry is the cause of it.
Then in 1990, I started regular intensive meditation practice. Slowly through meditation the IF became "INNER FOCUS". The mind became more disciplined.
I realized that my doings are not as important, as I naturally suppose. Success and failures do not, after all, matter very much. Even great sorrows can be survived; troubles or events that seem as if they will put an end to happiness in life fade with the lapse of time, until it becomes almost impossible to remember their poignancy.
Life was bringing many experiences and I realized that mere ‘conscious conviction’ or a ‘conscious belief’ does not free me from worrying.
I now embarked on a search, “Can I selectively erase old unwanted memories? Is it really possible to erase unpleasant memories?”
The IF (Inner Focus) revealed:
The subconscious (or unconscious) is the repository of intense emotional thoughts which were once in the consciousness. Thus evolved a technique of CRUM – Consciously Reprogramming the Unconscious Mind. I started using it myself and shared it with people as they came to share and discuss their issues and problems with me. The method was simple but very effective, it involves bringing the painful situation to mind, and then instead of brooding over it, immediately and deliberately plant (burry) positive thoughts (positive memory) through intense focus.
I found that memory is selectively programmable. Memory is open to disruption for a short period following each time this memory is recalled. It means that it is possible to recall an incident and, immediately after the act of remembering, simply activate a "memory eraser" and wipe it out, or “memory modifier” even though years may have passed since the original memory was formed.
Let’s understand this, for instance, a certain food can bring up memories of taste – delicious or disagreeable; a person can be remembered in pleasant or unpleasant contexts, and so on. When we next taste the food or see the person, all of the associated memories are called up in the blink of an eye, but in the end, only one of those memories will dictate our reaction (e.g. become dominant.) This memory will decide whether we will eat the food or reject it, or whether we will smile at our acquaintance or ignore him.
So, CRUM technique simply requires to bring into consciousness a past unpleasant experience, but NOW 
re-visualize the incidence in a positive perception (visualization). This erases the past memory and replaces it with new memory. When threatening or misfortune situation are in face, one can consider seriously and deliberately, for a short time, what is the worse that could possibly happen? Will what happen to me have any cosmic importance? Then by repeating the process of CRUM, one should implant in the subconscious, “Well, after all that would not matter so very much”. It has a dramatic positive result. One stops shirking from facing the worst possible issue. Regular practice of CRUM reduces psychological fears and diminishes worries. You experience a feeling of exhilaration. You gradually learn to ‘Face the Fear’ instead of running away from it. You will soon understand that it is wrong to distract the thoughts of psychological fear by thinking of something else or to distract our mind by indulging in some amusement or pleasure, for the problem do not get solved but get dis-solved.
Recently, a visitor brought to my attention that scientific research confirms my own observations. A team of scientists, have now found chemical methods for erasing memories selectively.
Every memory that we acquire undergoes a "ripening" process (consolidation) immediately after it is formed, this process makes memory impervious to outside stimulation or drugs that would obliterate it.
Until recently, science believed that for each separate item of memory, consolidation occurs just once, after which, the time ‘window’ that allows for "memory erasing" closes (usually about an hour or two after the memory is acquired).
However, evidence has lately come to light that a memory is open to disruption for a short period following each time this memory is recalled. If this is true, it means that it would be possible to recall an incident and, immediately after the act of remembering, to activate a "memory eraser" and wipe it out, irrespective of how old is the memory.
The CRUM technique can especially be significant when it comes to the kind of traumatic memories that are debilitating to those experiencing them. This finding may lead to new treatments for psychological trauma.
