Health can be a tricky issue especially if you are experiencing health problems which are 'in your face'.

Two methods work for me: 1. Logic 2. Focused meditation.

Logic I try and reason out a few things (which are obvious). When I get a bruise or scratch my hand or break a bone, what is the body doing? It is consistently and persistently trying to heal the bruise, scratch or break. That is the very innate nature of our body. We see the bruise fading in a few days; We see the scratch healing in a few hours, closing, forming a protective crust on the wound. This is the very nature of our body and if it does that on a small level, it also does that with bigger conditions or diseases. So, the body is always on your side, or its side. I know therefore, that my body is healing itself on a constant basis.

Focused meditation: I know that we are all vibration and my body is no different. I also know that my imagination makes reality. Therefore, I meditate in a focused way, first by talking to my body in a loving and appreciative manner. Then I imagine a healing light coming through my crown and filling up my body and giving my cells more nourishment to help it heal. I believe that this is occurring. I do it daily mostly before I sleep.

I have improved my skin, my hair, my eyes with this. I hope it helps.

concentrate as nearly as possible in accordance with the method outlined in this lesson; let there be no conscious effort or activity associated with your purpose. Relax completely, avoid any thought of anxiety as to results. Remember that power comes through repose. Let the thought dwell upon your object, until it is completely identified with it, until you are conscious of nothing else

The key phrase is "anxiety as to results".

If you are completely identified with the objection of your concentration, you are not trying to force anything to happen with it. You are completely in the moment. You are not giving any thought to how things presently are. Your current reality is irrelevant, and just fades away into the background.

When you are successfully in this state, you have no negative emotion associated with it.

You either feel good or neutral about what you are concentrating on.

Complete relaxation is the key to any of the exercises (any part). The systematic mandatory steps required to do any of the exercise are:
1. Complete relaxation and let go - There are various techniques to do this. The immediate one that comes to my mind is just sit quietly with open or closed eyes- Does not matter much. If you feel fierce emotions in your mind, imagine it to be a desert storm. To control desert storm, you do nothing else but to watch. Let the sand storm settle down. Settling down the thoughts is the first step which leads to the next step i.e silence. To feel more happier, think of happy thoughts related to happy incidents.
2. Silence - Once all the uncontrollable emotions settle down, the number of thoughts coming to mind will reduce and eventually you will experience silence. It feels like you are in a vacuum when that happens
3. Exercise in hand for a given part. This is a summary/extract/insight obtained by reading all the bullet points over and again. I find it very interesting how an insight develops by reading the points. Being an electrical engineer by profession, I have developed great insights that apply to me.
