We find ourselves in an imperfect condition. A state where things have to be in moderation/balance. A person can eat too much we can try too hard and have breakdowns due to too much opposition, we can know too much as the saying goes 'he had more intelligence than he can control. But in the perfect realm it is not so, nothing can hurt you because it is eternal, no flaw, no mixing. It is exactly on the dot, the way it should be, therefore it can not be overdone.
