Book excerpt: Bestselling author John Green provides a foreword to this deluxe edition of the beloved classic With a gorgeous new package and a foreword from bestselling author John Green, the deluxe edition of The Golden Rule spreads the message of kindness to a new generation. But, what does it really mean? And how do you follow it? A grandfather explains to his grandson that the Golden Rule means you “treat people the way you would like to be treated. It’s golden because it’s so valuable, and a way of living your life that’s so simple, it shines.” The book reveals versions of the Golden Rule found in many cultures and religions, including Christianity, Judaism, Buddhism, and Islam. Following the Golden Rule is something everyone can do, which means that every person—old or young, rich or poor—can help make the world a better place.
