The I Ching text is made up of 64 hexagrams. A hexagram is named thus because it appears to be 6 horizontal lines (爻 yáo) stacked one on top of another. In a hexagram, the line is either Yang, a solid or continuous line. Or Yin, a broken line with gaps in the middle. Traditionally, you count the lines of a hexagram from bottom to top. This way, line one is the line at the bottom and line six is the topmost one. Hexagrams are actually produced by the original 8 trigrams. These trigrams are combined in diverse ways to produce the 64. Each of these hexagrams comes with an obscure commentary that is quite comparable to a parable. Every line that is in a hexagram also comes with the same description.
