Energy, in itself, is a truth, a constant. Whatever gives out negative energy is imperfect and the otherwise is perfect. I can’t decipher what the idea of perfection is and where did it originate from but this is my opinion on the subject of perfection.
We cannot rely on opinions and thoughts of other people to determine right or wrong but our intuition. Intuition, according to me, is a energy that vibrates at the frequency of what is (what we call truth).
When we feel any negative energy such as feeling bad or hurt by someone, we can judge them to be wrong. If we feel otherwise, we can judge them to be right. When we cannot point out any mistake in anyone or anything, we deem it perfect and imperfect if the case is otherwise. For me, the answer to the definition and extent of perfection lies within all of us.
