Enlightenment is not conceptual. Zen Buddhists explain that as soon as you start to conceptualize, you set up duality. One becomes two: you the thinker and the idea or concept you are thinking about. Then comes further division: I like this; I don't like that. This is right; that is wrong. These dualities are the source of problems and suffering. According to Buddhism, dividing up our world in this way is false. Things do not either exist or not exist, they do both. Everything is just as it is, and the enlightened person perceives things just as they are.
