“When you look at a leaf or a raindrop, meditate on the conditions, near and distant, that contributed to the presence of that leaf or raindrop. Know that the world is woven of interconnected threads. This is because that is. This is not because that is not. This is born because that is born. This dies because that dies.” The leaf, as the Buddha implied, is both a discrete entity—a thing—and a process that derives from sun, sky, and earth: light, photosynthesis, rain, organic matter, and minerals and perhaps even the activity of humans and animals.
