Healing is a necessary ingredient  in spiritual evolution because it teaches us about illness as a mechanism of manifestation of the Soul. True healing comes from the depth of the Heart when we recognize the body as a holographic representation of the Soul’s voyage in the physical dimension. That is when we look for the origins of any disease not only in the environment physical conditions but also at the patterns of consciousness and conditionings that we carry with us into life.  Conventional medicine usually takes care of symptoms that arise from the surface and not of it’s routs that originate in emotions not delt with self consciousness.

Only the conscious Soul can look and find a true factor of disease and  keep the body alive and it's trillion cells in harmony together. Emotional conflicts within as the language of the Soul are stored as information in the subconscious, many times in forms of masseges, symbols, archetypes and belief systems and then when untreated pass to the unconscious and manifest. We can penetrate the subconscious and read this registered information in the body through meditation and prayer directly or get help from someone who can read it for us and disscover what the soul wants to tell us about ourselves. There is always a simple and direct relation between an illness, the organ where it appears, where, how and when it manifested and the abstract quality of consciousness that it represents.

For example, if we look at the general case of cancer, it means an unconscious  contradiction between the wish of the Soul to continue experiment itself in time-space and it's will to rest and unfold back into the Source. The reason is usually an emotion which contradicts our confidence in life and causes an expending fragmentation of our identity. The physical organism where it began represent a quality through which our consciousness was socked at least once but usually even more. Once we expose and embrace the hidden eoptional experiences interwoven into the tissue of consciousnes  - our body  - a spontanious, gradual or sudden natural healing can take place. Some healings, however, end with a physical death, when the Soul decides to take the lesson into the next life reencarnation or has evolved to maturity and resolved the need to experiments and explore life so that it wishes to eternally dissolve back to the Source.

Looking at disease as an opportunity of spiritual growth is not a new trend in modern spirituality and it is often called alternative medicine where abundance of  "techniques" of healings can be encountered in books. But the main question I would like to ask is whether the human race could reach a stage of spiritual growth without any illness and experience itself as forms of consciousness that excludes suffering. I suggest that it is only partially possible because of human mixed genetics of mammels-alien origins that imposes boundaries of food-sex-sleep as well as  illness and that we will need to change our genetics if we decide to reach that final step in evolution.
