Existence of this universe, I do not tire of drawing or attention to it. It's the most common thing underlying our experience that is everywhere you find this isness. Here is God hidden in plain sight. Being itself, which makes possible the existence of existing things. Just as gold makes possible theexistence of golden ornaments. Clay makes possible the exists of clay pottery. Water makes possible the exist of waves and foam and surf and water drops. All real things depend upon existence for their existence. T-E-N-T-E-S existence existing things. This is what Heidegger ran up against when he came very close to this idea.
