Therefore, keep happy.
Happiness brings the right vibrations throughout the mind and body, partly through the Solar Plexus and the Sympathetic Nervous System. Only lately have we begun to realise the importance of the rate and character of vibrations. Let the same elements vibrate differently, and we have ice or water or steam. We know the full and elastic firmness and resilience of faith, the shrunken and paralysed trembling of fear. It is largely a difference of vibrations. Happiness has the most desirable vibrations.
Happiness means that we inhale more life-giving and cleansing oxygen, and exhale more carbonic acid and other waste matter.
Happiness means that we have better sleep, and can do with less sleep.
Happiness means improved circulation. It keeps the body warm in winter and cool in summer. It relieves the physical heart.
Therefore, keep happy.
Happiness gives better looks. It makes the eyes brighter, the complexion clearer, the step more vigorous, the carriage more upright.
And, generally, Happiness makes people more attractive. It has a marked social value.
