In Plotinus' Ennead 3.8.10, you will find, "Once you have uttered "The Good," add no further thought..."
ACIM Lesson 169, "We say 'God is' and then we cease to speak."
This is what I mean when I say ACIM is the same as Plotinus' Enneads. I could quote the Bible or some Sutra. But this is not a scholarly essay. It is my musings on what I am studying. I mean, before The One, our little words go silent. But to get before The One, I must enforce silence myself.
No it is not an endless do loop. Be quiet and you will find Silence.
I don't know why some people seek to know God and others don't give God a second thought. I'm one of the ones who aspires. I get up at 3:30 in the morning to give Silence It's time.
