The Teachings of The Buddha are not explaining how “the world should be” through rules, commandments, or beliefs and the world becomes more peaceful through everyone following those rules and beliefs.
Instead, The Buddha explains how “the world is”, as part of The Natural Laws of Existence, so that you can gain wisdom of these natural laws to train the mind allowing you to navigate the world through wise decision making that produces wholesome results (i.e. wholesome Kamma) for an improved condition of mind and life so that you can then experience complete peacefulness and joy.
