The glue that holds the natural world together appears to be a harmonious balance of opposites: day and night, light and dark, winter and summer, liquid and solid, acidic and alkaline, male and female, wave and trough, proton and electron, etc. There prevails in our reality an explicit duality that represents an implicit unity (the “oneness” about which I’ve previously babbled), and the line of separation between those things just named is as thin as it is necessary: yang rubs up against yin, yin against yang, distinct but mutually supportive.
