Hold fast to your most indefinite, waking dream.

You must walk sometimes perfectly free, not prying or inquisitive, not bent on seeing things. Throw away a whole day for a single expansion, a single inspiration of air. You must walk so gently as to hear the finest sounds, the faculties being in repose. Nature will bear the closest inspection. She invites us to lay our eye level with her smallest leaf, and take an insect view of its plain.

I have been as sincere a worshipper of Aurora as the Greeks.

White Pond and Walden are great crystals on the surface of the earth, Lakes of Light.... They are too pure to have a market value;they contain no muck. How much more beautiful than our lives, how much more transparent than our characters are they! We never learned meanness of them.

Nature confounds her summer distinctions at this season. The heavens seem to be nearer the earth. The elements are less reserved and distinct. Water turns to ice, rain to snow. The day is but a Scandinavian night. The winter is an arctic summer.

The eye is the jewel of the body.

One must maintain a little bittle of summer, even in the middle of winter.
