So, the non-dual realization is, as the teachings say, “All that is, is That.” (Call it “God,” if you want: but it is not a God that is apart from you; you and God are the same, singular actuality. As are all things.) Consequently, there is nowhere you need to go and nothing you need to do in order to be “one” with God. To comprehend this is the non-dual realization, so-called enlightenment – Robert Wolfe
