Simplicity in forms of worship, opposition to violence, and the importance of compassionate living and thoughtful listening are hallmarks of the spirituality of the Quakers. From their beginnings in seventeenth-century England to today, the Friends have attempted to live out their belief in the presence of God's spirit within their hearts. This book features the writings of some of the most influential and inspirational Quaker thinkers -- George Fox, John Woolman, Caroline Stephen, Thomas Kelly, and others -- providing a vivid portrait of the beautiful, simple spirituality of the Quakers.
