It can start with physical disharmony or mental disharmony – one acts upon the other. What causes disharmony? A lack of tone which is the life energy or vital force, in addition to, a lack of rhythm or the regularity of the beating of the pulses and circulation of blood through the veins. A body that is already lacking in health is more susceptible to illness than a perfectly healthy body and a mind which already has a disorder is more susceptible to suggestions of disorder, going from bad to worse. Illness attracts illness, disharmony attracts disharmony and harmony attracts harmony.
