To the Buddha, everything is a dharma, a mental event. We don’t really experience the world, he observes; we experience constructs in the mind made up of information from the senses. This information is already a kind of code. We don’t actually see things, for example; we interpret as separate objects a mass of electrochemical impulses received by the brain. And of course this information covers only a narrow range of sensibility, limited to what the senses can register. But from this scanty data the mind makes a whole world.
