Because the illness is not the origin of the predicament but merely a manifestation of the original root problem.
For example, if someone has issues with their lungs it can be the result of being in a codependent or smothering relationship. Therefore the focus of healing must address the dysfunctional relationship as well as the lung condition.
Another persons lung issues may come from working in a chemically toxic environment. In that event the healing must focus on eliminating the toxic chemicals from the body as well as changing the pattern that constrained the client to end up in this harmful work situation.
If only the manifestation of a condition but not the true root problem is being treated, the manifestation might get better but the root problem will persist and find another way to come to the surface.
Any condition or illness has a message for you.
Something in your life is not in harmony with your true being and will come to the surface until you understand the message.
By focusing on the origin of the illness and not only the illness itself, we are paying attention to the soul's message. Once you have discovered the origin and created a shift on the consciousness level the true healing can take place.
I have found this knowledge very helpful in my work as an Akashic Records Consultant and Teacher. Numerous testimonies have confirmed that healing occurs when you focus solely on the origin of your problem and not on the disease itself.
Once you understand the variety of causes that can be responsible for one condition, you can embrace the fact that all the possibilities of healing have their purpose. There is no better or worse healing modality, superior or inferior to another. The only thing that matters is that it is the right modality for you.
With all my love,
