Negative thoughts poison life

Thoughts of worry and thoughts of fear are fearful forces within us. They poison the very sources of life and destroy the harmony, the running efficiency, the vitality and vigour.

While the opposite thoughts of cheerfulness, joy and courage, heal soothe, instead of irritating, and immensely augment efficiency and multiply the mental powers. Be always cheerful. Smile. Laugh.
