So what does nonduality actually mean? It means your experience of your deepest self and my experience of my deepest self and any other human being’s experience of his or her deepest sense of self is One. It’s one and the same self…. You and I may appear to be at two different points in space. But my deepest self and your deepest self are the same self… The interior of all things is One.
