When heaven and earth are in communication with each other, all things in consequence will have free course. When the high and the low (superiors and inferiors) are in communication with one another, they will be possessed by the same aim.——- from The Tuan, Tai
Modern interpretation: Living things in the natural world grow smoothly when meteorological phenomena and environment are in communication with each other. Likewise, a good communication between the high level and the lower level will achieve the common objective.
Moral: Each and every citizen is responsible for the protection of the earth’s environment.
Glossary: With Kun above and Qian below, the Hexagram Tai has the image of heaven and earth, and lord and minister. Kun represents everything, including human will. In meeting, things communicate. In communication, people become like-minded.
