in Thoreau’s Journal:
These regular phenomena of the seasons get at last to be (they were at first, of course) simply & plainly phenomena or phases of my life. The seasons & all their changes are in me. I see not a dead eel or a floating snake—or a gull—but it rounds my life and is like a line or accent in its poem.
Almost I believe the Concord would not rise and overflow its banks again, were I not here. After a while I learn what my moods and seasons are. I would have nothing subtracted—I can imagine nothing added. My moods are thus periodical, not two days in my year alike. The perfect correspondence of Nature to man—so that he is at home in her!
