Walter Russell Quote

Joy and happiness are the indicators of balance in a human machine, just as a change in the familiar hum in a mechanism immediately indicates an abnormalcy to the practiced ear of the mechanic. An inner joyousness, amounting to ecstasy, is the normal condition of the genius mind. Any lack of that joyousness develops body-destroying toxins. That inner ecstasy of the mind is the secret fountain of perpetual youth and strength in any man. He who finds it finds omnipotence and omniscience.
