For example, when we visualize a circle, we imagine it as it exists in the invisible realm, but applying it to the visible world removes its perfection.
Unless the invisible world is where perfection is and that, we cannot see it so we are unable to see perfection, so we are imperfect and perfection is only conceptualized in our imagination.
So as long as perfection exists only in our minds everyone's idea of God can be as they choose to make it. It seems that visualizing anything is in the mind rather than an invisible world because it's visible to me. A mental visible circle may be perfect but is has no personality, does not communicate, has no biological life, etc. I find it impossible to visualize a God, perfect or imperfect. It seems this does not apply to living things.
