I call him religious who understands the suffering of others.
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.
There is nothing that wastes the body like worry, and one who has any faith in God should be ashamed to worry about anything whatsoever.
