Within the literal language of the Bible is a deeper spiritual meaning that points the way toward a greater understanding of faith and of our own role in the world. Eighteenth-century scientist and theologian Emanuel Swedenborg described that inner language of the Bible as "correspondences." More than a century later, John Worcester used Swedenborg's teachings as the foundation for a three-volume road map to the correspondences of the natural world. Correspondences of the Bible remains one of the most highly regarded references on the subject today.

Plants represent the more passive characteristics of our personalities, living examples of how knowledge takes root in our mind and how that knowledge inspires us to act. Every part of a plant has its own special meaning, from its seeds and the shape of its leaves to the sweetness of flowers and fruit. The Plants shows us how we can draw spiritual inspiration from the plants we use every day for food, clothing, shelter, and decoration.
