The 4 Noble truths, there not avoidable there not scientific as such they just are, well the truth, all backgrounds and religions wether budhist or not will go through these truths, how they recognise them or act upon decides weather or not they are budhist. Number three, is the Cessation, I assume this means accepting you can not change what has happened to you need to look to the present time and act accordingly to prevent spiraling despair and other sad , angry emotions taking over make the future dark and unhappy. I did not notice, the Fourth truth in there, maybe I missed it but I re read it a few times and did not notice it so I can not comment. I see it as if you allow yourself to feel negatively, if you blame yourself you will never be able to to cease the feelings where as if you accept and move on you can reach an inner peace so to speak. is this the basic principle of budhism, letting go of pain and suffering for yourself and wishing well on others in the hope that one day they too will be able to not take the negatives personally and let them go. Is it ok to intervene if you see a loved one suffering, and try to walk them through the noble truths or is this against the beliefs.
