Perfection is the exclusive attribute of God, and it is indescribable, untranslatable. I do believe that it is possible for human beings to become perfect, even as God is perfect. It is necessary for all of us to aspire after that perfection but when that blessed state is attained, it becomes indescribable, indefinable.
Each one has to find his peace from within. And peace to be real must be unaffected by outside circumstances.
