There is an Indian proverb or axiom that says that everyone is a house with four rooms, a physical, a mental, an emotional and a spiritual. Most of us tend to live in one room most of the time but, unless we go into every room every day, even if only to keep it aired, we are not a complete person. – Rumer Godden, A House with Four Rooms

To keep the body in good health is a duty… otherwise we shall not be able to keep our mind strong and clear. – Buddha

The human body is the only machine for which there are no spare parts. – Hermann M. Biggs
