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.
