Hexagram 23 of the Yijing, or the Book of Changes. The hexagram consists of five broken lines at the bottom with a solid line at the top. Bo means "peeling," and the "judgment" of the hexagram reads, "It would not be fitting should one set out to do something." For more information on this hexagram, see Richard Lynn, tr., The Classic of Changes (New York: Columbia University Press, 1994), pp. 280-5, or Wilhelm/Baynes, tr., The I Ching or Book of Changes (Princeton, Princeton University Press, 1977), pp. 93-96.
