Joy and happiness are the indicators of balance in a human machine…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.
~ Walter Russell Quotes from The Man Who Tapped the Secrets of the Universe
