Most men carry their souls in the medulla. – Martin H. Fischer (1879–1962)

Good for the body is the work of the body, good for the soul the work of the soul, and good for either the work of the other. – Henry David Thoreau

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
