Book excerpt: These are unique stories of timeless wisdom and understanding from the Zen Masters. With rich and fascinating tales of swords, tigers, tea, flowers and dogs, the writings of the Masters challenge every perception - and seek to bring all readers closer to enlightenment. Throughout history, some books have changed the world. They have transformed the way we see ourselves - and each other. They have inspired debate, dissent, war and revolution. They have enlightened, outraged, provoked and comforted. They have enriched lives - and destroyed them. Now Penguin brings you the works of the great thinkers, pioneers, radicals and visionaries whose ideas shook civilization and helped make us who we are.
