For the most part, our habitual mode of being in the world is that of a kind of obliviousness where we are not particularly paying attention to our experience.
In this mode we experience through our narratives, abstractions and reflections and posit a world of discrete self-existing entities - a world of happened (past tense) things. This results in the illusion of separation.
Look… presently, no thing has happened - the only thing that is real is this happen-ing… now… this unmissable event of Existence. This is the fabled Oneness. There aren't two events - there is simply THIS as it presents.
