"A Rule of life is a pattern of spiritual disciplines that provides structure and direction for growth in holiness…it is like a trellis, (it) curbs our tendency to wander and supports our frail effort to grow spiritually…. It fosters gifts of the Spirit in personal life and human community, helping to form us into the persons God intends us to be." (Marjorie J. Thompson Soul Feast)

If you don't have a rule of life defined by spiritual practices- something else is ruling your life.
