If a tree can imagine, it likely has a soul (そう). Its soul is what makes it possible for the tree to contemplate things, you see?
Use your soul to imagine what this tree is imagining with its soul. Is it contemplating the deep mysteries of the universe? Is it imagining where that squirrel has gone off to?
