They learn from the cell life within their own bark the difficulties of survival. They see the life around them and know death intimately, as the trees next to them often fall and die. But the trees learn through all this experience that life never dies and is never wasted. They cannot move about and therefore we think of them as having less life experience, but that is where we are mistaken. It is not through rushing about that one learns, but from taking into oneself the experiences from without and thus feeling the pulse of life beating within. Humanity tries to escape from experience which is often suffering. When it rains we go to shelter; when death comes we put away the sight of it. The trees let life beat against them, and try to withstand it.
