Following are excerpts taken from The Power of Positive Thinking, by Remez Sasson.

"A positive mind anticipates happiness, joy, health and a successful outcome of every situation and action. Whatever the mind expects, it finds.

Not everyone accepts or believes in positive thinking. Some consider the subject as just nonsense, and others scoff at people who believe and accept it. Among the people who accept it, not many know how to use it effectively to get results. Yet, it seems that many are becoming attracted to this subject, as evidenced by the many books, lectures and courses about it.

Positive and negative thinking are both contagious. All of us affect, in one way or another, the people we meet. This happens instinctively and on a subconscious level, through thoughts and feelings transference and through body language. People sense our aura and are affected by our thoughts. Is it any wonder that we want to be around positive persons and shun negative ones?

The power of thoughts is a mighty power that is always shaping our life. This shaping is usually done subconsciously, but it is possible to make the process a conscious one. Use positive words in your inner dialogues or when talking with others. Smile a little more, as this helps to think positively.  If you persevere, you will transform the way your mind thinks.

Once a negative thought enters your mind, you have to be aware of it and endeavor to replace it with a constructive one. Persistence will eventually teach your mind to think positively and ignore negative thoughts. 

It does not matter what your circumstances are at the present moment. Think positively, expect only favorable results and situations, and circumstances will change accordingly. It may take some time for the changes to take place, but eventually they do.”

The following are excerpts taken from Deepak Chopra's book
Quantum Healing: Exploring the Frontiers of Mind/Body Medicine:

In Ayurveda, a level of total, deep relaxation is the most important precondition for curing any disorder.  The underlying concept is that the body knows how to maintain balance unless thrown off by disease; therefore, if one wants to restore the body’s own healing ability, everything should be done to bring it back iznto balance.

Research on spontaneous cures of cancer, conducted in both the U.S. and Japan, has shown that just before the cure appears, almost every patient experiences a dramatic shift in awareness.  This leap in consciousness seems to be the key.  It does not have to come in a flash, however.  The word most commonly used among scientists for such a jump is quantum.  The word denotes a discrete jump from one level of functioning to a higher level – the quantum leap.  (Deepak Chopra, M.D., coined the phrase quantum healing to clarify miraculous healing as a result of a changed mindset.) 

The reason why curing cancer by yourself is a miracle but mending a broken arm is not comes down to the mind-body connection.  The broken bone seems to mend itself physically, without the intervention of your mind; yet, a spontaneous cure from a life-threatening disease depends on a special quality of mind, some deep will to live, a heroically positive outlook, or some other rare capacity.  What this implies is that there are two kinds of healing: one that is normal, and the other abnormal or exceptional.  But is this true?  What marks a survivor as opposed to a non-survivor?  Apparently, the successful clients have learned to motivate their own healing, and the most successful have gone much further than that – they have found the secret of quantum healing.  Modern medicine cannot even begin to duplicate their cures, because no cure that relies on drugs or surgery is so precisely timed, so beautifully coordinated, so benign and free of side effects, so effortless as theirs.  Quantum healing moves away from external, high-technology methods toward the deepest core of the mind-body system.  This core is where healing begins.

Gifted with total flexibility in our nervous systems, we all have the choice to build boundaries or tear them down.  Every person is continually manufacturing an infinite array of thoughts, memories, desires, objects, and so on.  These impulses, rippling through the ocean of consciousness, become your reality.

From the despair of disease, one can discover joy.  At the moment when the memory of health is returned, it can bring enough power to last a lifetime.
