oneness of delusion and enlightenment ［迷悟不二・迷悟一体］ ( meigo-funi or meigo-ittai): Also, non-duality of delusion and enlightenment. The principle that delusion and enlightenment are, though different in aspect, one and the same in their essential nature. A bad cause or influence gives rise to delusion, and a good cause or influence, to enlightenment. Delusion and enlightenment are two different workings, but both arise from the essential nature of life. This Mahayana concept contrasts with the Hinayana view that enlightenment and delusion, or enlightenment and earthly desires, are mutually exclusive and incompatible.
