“Articulate the word ‘Sun’ and you soon find yourself thinking of the Moon. Man and Woman, Love and Hate, Right and Wrong, Farmer and Shepherd, Left and Right, Queen and King, North and South, Positive and Negative, Heaven and Hell, East and West, Life and Death, Victory and Defeat, Earth and Sky, Sunrise and Sunset. So, two is an inauspicious number in its cracking of unity.”
