Yes. You have to step outside the house to see the sun lighting the ground beneath your feet. But the sun is always shining. Just not always in view.
I would not use the expression as you have that, God "seek to manifest HImself". God does not seek. God Is. God is always manifesting, in every single nanosecond of every single eon since the Big Bang in this Universe. It always shines, always manifests, always creates, endlessly, ceaselessly, through Itself to all of Creation. This ceaseless shining and manifesting is OM, is it not?
Again, I very much agree with you that someone has to come to seek this in themselves. It is not apparent to most of our minds because we daydream inside our heads all day about what constitutes reality. Thousands upon thousands, millions, billions, walk through every day in a daydream of the minds, each in their own realities.
We live inside the houses of our heads, not seeing the Shining of the Manifest Divine in everything before us, every single moment of every single say, lives upon lives up lives, endlessly. God never moves. God never stops Shining. It is only when we "look up" out of our little houses and see Reality, that we know we are God.
And all the rest of this, was an illusion.
