The character "屯" signifies the beginning of all things. This hexagram is generated by the mating of "Heaven" from the Qian (乾) hexagram and "Earth" from the Kun (坤) hexagram. The lower trigram (Zhen 震) transforms from the Qian hexagram by one yang line entering the Kun hexagram, replacing the yin line at the initial position with a yang line. Furthermore, this yang line desires to ascend and unfurl. The upper trigram (Kan 坎) is formed when one yang line from the Qian hexagram mates and enters the Kun hexagram, replacing the yin line sandwiched in the middle with a yang line. This signifies a "yang" being trapped between two "yin" lines, experiencing distress. It is comparable to grass and trees: this hexagram represents seeds sprouting in the soil and emerging above the surface. It is like a tender sprout, just emerged, being tormented by the fragility it experiences in the face of wind and rain. In terms of "humans," it corresponds to the infant stage. In terms of a nation, it signifies the period of founding and establishing a new enterprise. Because this hexagram is born from the initial union of heaven and earth, it is thus named the "Tun" hexagram.
