A thin place is anywhere our hearts are opened….There are many kinds of thin places. Some are “secular” in that they are not explicitly religious. For example, nature, especially wilderness areas, can sometimes become a thin place. The combination of an untamed world with solitude and quiet can yield moments when we experience “the earth filled with the glory of God.” For some, the arts can become a thin place. Music, poetry, literature, the visual arts, and dance can all become thin places in which the boundary between one’s self and the world momentarily disappears.
