Education aims at full and harmonious development of all the faculties of man. A person is like a rough diamond that needs cutting and polishing before all his mental and physical powers can function properly. Education fully develops and polishes human personality, so that a person needs a better life physically, mentally and spiritually. Education is useful for body, mind and spirit. It keeps the body fit and mind sound and the spirit fine. A sound mind in a sound bodyis a well-known saying. Bodily strength ensures intellectual activity. A healthy person is capable of hard efforts and living without effort is useless.
