Without imperfection there is no perfection. Once we see imperfection we strive for perfection. Once we realize that we have imperfection in whatever ways i.e. outer in materialistic world we learn from our imperfection and resolution for perfection. In the same way if we discover imperfection inside us, we try for perfection. Eventually we try to find who and what is perfect internally and learning ways of perfection. That way we complete the outer and inner review of perfection.
