From the “Fabrication and Impermanence” chapter of What Makes You Not a Buddhist by Dzongsar Jamyang Khyentse:
Consider cooking a hen’s egg. Without constant change, the cooking of an egg cannot occur. The cooked-egg result requires some fundamental causes and conditions. Obviously you need an egg, a pot of water, and some sort of heating element. And then there are some not-so-essential causes and conditions, such as a kitchen, lights, an egg timer, a hand to put the egg into the pot. Another important condition is absence of interruption, such as a power outage or a goat walking in and overturning the pot.
I love that last line. Freakin’ goats….
