"Popular with collectors, storm pattern weavings feature a number of complex design elements. The box box at the geometric center is said to represent the spiritual center of the Navajo universe. From the center, four zig-zagging lines representing lightning bolts radiate to boxes in each quadrant or corner. These are said to represent the homes of the four winds or four directs or four sacred mountains bordering the Navajo world." paraphrased from Steve Getzwiller's publication The Fine Art of Navajo Weaving.
