I'm thinking of angels: traditionally the assistances of God, and about whether they are, and from this, what is "being" when the are so flued".  Two events make me wonder. A long time ago when I was coming out of a church I was aware, without any seeing, a pure "Isness". And the seconds was recent, looking at flock of distant birds swirling in the distance, that seeming beyond normal being, as this moment had a seventh dimension.
