The final segment in "Spirituality" features James Turrell, known for his use of light as the primary material in his work. From his Quaker Meeting House to his "Roden Crater" project, the artist has devoted his life to capturing the ethereal properties of light and its powers to evoke transcendence and the sublime. Pursuing his vision at a great sacrifice, Turrell wryly comments "People often ask me how much this crater costs. It cost me two marriages and a relationship." This segment focuses on two new works in Houston, Texas—an underground tunnel of light and a skyspace in the ceiling of a Friends meetinghouse—in addition to Turrell's life's work in Arizona's remote Painted Desert—the "Roden Crater."
