“Nonduality” (advayatva) = “Middle Path” (madhyamapratipat) = freedom from extremes of being and nothingness (antadvayavivarjita). For numerous references, see Lamotte, pp. 301-302, n. 1.
Nonduality is experienced as the nature of Mind — in which thought and the absence of thought are no longer mutually exclusive. This is ro-gÇig – the one taste.
Because non-duality points to something that already is here but is not clearly seen, when it is clearly seen the freedom that results is recognised to have always existed. This freedom is not a specific state of mind or a specific way of being but is ever-present regardless of states of body or mind (or environment). It could be said that it is understanding that leads to freedom, but freedom is beyond even understanding, understanding also being something that can come and go. Freedom cannot be put into words, it is unique, ever-present, already here and all that is.
In non-dual teachings, the basic teaching is that the sense of self that we presume ourselves to be is a fiction. What remains after this is seen is a mysterious and ordinary sense of ‘divine oneness’. One ramification of this teaching is that we can learn to see that we are not the authors of our own actions even though we appear to be. This is known as non-doership. This teaching is often stated explicitly in non-dual traditions such as Advaita Vedanta, Zen, Dzogchen and Taoism.
Non-duality says we don’t need to fundamentally change anything, we just need to better understand our present situation.
