that we seek to remove from our lives possessions and activities that would separate us from God and one another.
To Quakers, simplicity is a spiritual quality that denotes an inward centeredness, a singleness of being that is responsive to the Divine within. Simple living is a creative act that frees us from extraneous concerns and enables us to devote attention to the Divine. A simple life is often hard to achieve. It means consuming or collecting nothing in excess of what is needful for our health and well-being and understanding what that is. What is needful may differ from one person to another, but in general it means that which is not extrane- ous in terms of time, possessions, speech, and activities.
