The other form of a miracle is through the intervention of a higher determinism, or bringing into play higher forces than the physical, say vital (pranic) and mental energies for example. These forces may intervene, changing the course of illness or may simply superimpose themselves on the physical manifestations of illness leading to temporary reprieve. The illness may then remain dormant for years but may never leave completely. It can also erupt again after a certain period. Or else a new malady may appear in place of the old one. Otherwise it might stay as an undercurrent of life, maiming us from within, even though we may seem to be free of the illness from outside.
These interventions sometimes appear miraculous since they relieve and heal without the aid of physical methods. We are so used to thinking and believing that material forces are the only effective means that we feel any other intervention without material support is truly miraculous. But if we look behind the magic and try to understand the play of forces, then we discover that even this is effective only to the extent that the body consciousness secretly supports the will to cure and the mind gives assent through its faith in the process. In reality, the body is cured only when it has decided to be cured and the means it uses is the one in which it has faith.
