Lankavatara Sutra

False-imagination teaches that such things as light and shade, long and short, black and white are different and are to be discriminated; but they are not independent of each other; they are only different aspects of the same thing, they are terms of relation, not reality. Conditions of existence are not of a mutually exclusive character; in essence things are not two but one.

Things are not as they seem - and nor are they otherwise.
