Passage Four

     From good reading we can derive pleasure, companionship, experience and instruction. A good book may absorb our attention so completely for the time being that we forget our surroundings and even our identity. Reading good books is one of the greatest pleasures in life. It increases our contentment when we are cheerful, and lessens our troubles when we are sad. Whatever may be our main purpose in reading, our contact with good books should never fail to give us enjoyment and satisfaction.

      With a good book in our hands we need never be lonely.   Whether the characters portrayed are taken from real life or are purely imaginary, they may become our companions and friends. In the pages of books we can walk with the wise and the good of all lands and all times. The people we meet in books may delight us either because they resemble human friends whom we hold dear or because they present unfamiliar types whom we are glad to welcome as new acquaintances. Our human friends sometimes may bore us, but the friends we make in books never weary us with their company. By turning the page we can dismiss them without any fear of hurting their feelings. When human friends desert us, good books are always ready to give us friendship, sympathy and encouragement.
