And that view is an ominous one. A clap of thunder can only be heard for a few miles, not hundreds, so this text probably describes an earthquake rather than a thunderstorm. In ancient China people slept on mats, and beds were only used for convalescence. In this text a healing ceremony is being conducted. The character xun depicts two people kneeling, perhaps before an altar.
Some scholars believe it is an eclipse that is being described here.
7 Kun is problematic because in the Zhouyi the character occurs only as the name of a hexagram. We are thus limited to the ideograph itself without further context. 9 Line 3 is the only line text of hexagram 1 that appears not to describe the seasonal migration of the Cerulean Dragon across the southern sky. All day long the dragon has been rising in the heavens, but at dusk when it is finally visible, it still is hindered from full flight. The rising dragon in the southeastern sky was the harbinger of spring, and full flight in the south was the height of summer.
