Lower half is a pine tree. Upper half is paper made from the bark of a pine tree. The peeled, boiled, and beaten fibers of the tree return to the same place again.

The natural world continues to circulate. If it flows, it will surely meet again. Everything is in continuity. Where does the bark of a pine tree end? Does it cease to be a pine tree when it becomes paper? Does it cease to be a pine tree when it dies?

Everything is in a superimposed state. It is paper, it is the bark of a pine tree, and it is dead. Everything is in a gradient, and everything affects each other. Therefore, everything in the past is connected. It may be a thin connection, but it flows inside. That connection leads to a reunion someday.
