We are dirt/dust, and to think any more of ourselves than that is just ego talking, and does not really benefit us in any kind of way, anyway, etc...
Yes we are all also spirit, but the way we are all one, or will become one, is when all the parts of the body fall in line with the will of the One who is the head, and again, thinking any more of ourselves than it/that/this, is just ego talking, and does not really benefit us in any kind of way, anyway, etc...
We are all only parts of the great body of the One who is the head, etc, and right now, we are not that yet, because we are all not yet in line with the will of the One who is the head, etc, so we are nothing more than fallen ones right now really, until that changes, etc...
We do not have a universe within us, but this universe is God's body, and He is the only One who is the great unifying consciousness, etc, but right now, His will is to not fully unify it all just yet, etc, because there are still some very important things for us to learn here, like lessons in "humility" for one, just yet, etc...
He can't afford to allow one's into Heaven for an eternity that would just cause it all to fall all over again just yet, etc...
That was for the beginning, but has no further place at or after a certain point, and in leading up to this creations final end, etc...
If everything is connected, then it is all connected by Him, and not us, etc, for we are only parts, etc, and we'd do very, very well to always be aware of, and always remember that, etc...
Pride makes one very, very stupid, and very, very unenlightened anyway, etc, for it strips away ones neutrality, and objectivity, etc, and so it also gets in the way of knowing the real Truth as well, etc...
God Bless!
