The law of perfection points to the necessity that everything is perfect as it is. In other words, nothing can be added or taken away from the way things are. That may sound counter to our own experience, but that is because we have biases and preferences. In itself the universe is pure perfection, including our ignorance and biases, they are the way they must be. This law is very powerful, it has the potential to liberate a mind from Samsaric wheel in a few minutes.
