The state of reality being equal to your vibration, as is indicated by your emotional state, thus makes your state of health also equal to your emotional state. Consequently, the more desirable is your emotional state, the more desirable is your state of health.
Therefore, the only possible cause of an illness is that of an emotional state that is equal in nature to that of the illness as is indicated by the emotional state produced by thoughts of the illness. Ergo, illnesses are counteracted by the displacing of such negative emotion with positive emotion. The greater is the degree of the positivity, and the more often it is experienced, the more the vibration of the illness is thereby displaced by good feeling emotions that coincide with wellness.
