The invisible life energy circulates inside of us and makes us alive. If this energy is low, so does our resistance to illness and stress. If this energy is high, so does our capacity to be healthy and happy.
If the flow of the Ki energy, which is the vital energy, is interrupted through internal or external cause, there becomes imbalances in physical and mental bodies that may result in illness. Therefore, every illness is a result of the interruption of the Ki energy, and the warning of our soul to correct our mistakes and get us back on the path of the truth.
Reiki is about raising our vibration rather than destroying the bad energies. It aims us to learn through consciousness rather than suffering. Reiki healing raises the consciousness of the person, so that he discovers the reason of his suffering. As a result of that, the thought pattern that creates the illness in the first place is healed as much as his body heals.
