The sky has dual faces, its expressions of day and night; the fluctuations of the meteorological face and what is beneath our day lit view, the more distant astronomical face. The physical layers that disclose and reveal are metaphors for ontological meanings; for revelation, insight, guidance.

The heavens keep telling the wonders of God, and the skies declare what he has done. Each day informs the following day; each night announces to the next. They don t speak a word, and there is never the sound of a voice. Yet their message reaches all the earth, and it travels around the world.

from Psalm 19 : the Bible
