The Earth Does Not Owe To The Sky

Even after all this time the sun never says to the earth "you owe me."
Look what happens with a love like that, it lights the whole sky.

Hafiz (Circa 14th century Persia)

Nature is an Excellent Schoolmaster

Earth and sky, woods and fields,
lakes and rivers, the mountain and the sea,
are excellent schoolmasters,
and teach some of us more
than we can ever learn from books.

John Lubbock
