"God is day and night, winter and summer, war and peace, surfeit and hunger"

This quote by Heraclitus talks to the concept of duality and the balance of opposites. He is suggesting that God is present in all aspects of life, both the excellent and the bad. He is saying that God is present in the day and the night, the winter and the summertime, the war and the peace, the surfeit and the cravings. This idea of duality is a common theme in Heraclitus' approach, as he thought that deep space was in a consistent state of flux and that the only thing that was continuous was modification. He thought that the balance of revers was necessary for the universe to exist and that God was the supreme source of this balance. By saying that God is present in all elements of life, Heraclitus is suggesting that God is the ultimate source of balance and harmony in the universe. He is likewise suggesting that God is present in all elements of life, both the great and the bad, which it depends on us to find the balance between them.
