Nonduality translates Sanskrit advaya and advaita, “not two”. It differs from monism in refusing to count: it denies duality without asserting a single thing. Advaita Vedānta, Madhyamaka, Dzogchen, Kashmir Śaivism and the Daoist sages each express it in their own terms, as do Christian and Sufi writers speaking of union.
Nonduality
“Not two”: the realisation that the separation of self and world, or self and God, is not ultimately real.
Also: nondualism, advaya
