Christians believe that you only have one shot at salvation and that is in this life......In Buddhism we see that there are many chances, many lives to accomplish salvation (enlightenment).
If you walk into the middle of a cultural situation that you know nothing about you could make things worse not better.
If you attach to injustice that is happening in Myanmar or anywhere for that matter, you have abandoned the Path. See the injustice and try to help but do not attach.
If one person attains enlightenment that is of far greater good for the world than if you feed a million.
