How hard to realize that every camp of men or beast has its glorious starry firmament for a roof. In such places, standing alone on the mountaintop, it is easy to realize that whatever special nests we make -- leaves and moss like the marmots and the birds, or tents or piled stone -- we all dwell in a house of one room -- the world with the firmament for its roof -- are all sailing the celestial spaces without leaving any track.
