What the world will become depends on the quality of human’s mind. When humans have pure minds, living a mindful life and doing positive Karmas including sharing, keeping the five precepts and meditating, the world will become peaceful in that era. The economy will be great. Climate will be pleasant. Only a few sicknesses will be found. Humans will live a long and happy life without hardship or obstacles. They will have a good complexion and everything they wish for.
