“Doctors agree that illness is caused through faulty food habits and foolish ways of spending leisure. But, they do not seem to know that food is a Word that connotes a wider variety of ‘intakes.’ Every experience that is drawn through any of the senses in ‘food’ has an effect on one’s health. We say “food for thought”; whatever we see or hear or smell or touch has an effect on the body; good or bad. The sight of blood makes some people faint; or, it may be some bad news, that administers a shock. Allergy is produced by unpleasant smells, or when something intrinsically unwelcome is contacted or tasted. A sound mind ensures a sound body; a sound body ensures a sound mind. The two are interdependent. Health is essential for happiness; happiness is a capacity to be happy, whatever may happen is essential for physical health, too. “

"All beings in creation are living by rendering mutual service and no one can be considered superior to another. Every person should render service according to his capacity and the sphere of his activities. There are various limbs in the human body. But the hands cannot do what the legs are capable of, nor can the eyes perform the duties of the ears. What the ears can enjoy, the eyes cannot. Likewise, among human beings there are differences. Their capacities and aptitudes may vary. But each should take part in service activity according to his ability, equipment and field of work".
