不二

advaya. No second, non-duality, the one and undivided, the unity of all things, the one reality、 the universal Buddha-nature. There are numerous combinations, e. g. 善惡不二 good and evil are not a dualism: nor are 有 and 空 the material and immaterial, nor are 迷 and 悟 delusion and awareness-- all these are of the one Buddha-nature.
