If you wanted to understand the soul of a forest, then you should find a stream in the forest that was surrounded by huge trees and walk from upstream to downstream once.
After going past the branches and a bush with blooming flowers, a most common stream could be seen! The flowing water was blocked by the tree roots in shallow parts, so it crashed into the roots and released gas bubbles naughtily. The water flowed from the north toward the south and passed through the forest. It faced many obstacles but paid no attention to any of those. It simply gathered into a kind of force that had never changed for a thousand years. It was just like the muscle that had to stiffen in face of an unavoidable fight.
