Reference request: the ways of the world I am looking for sutta text where the Buddha says something like...


  The ways of the world will never be finished find your own salvation
  with diligence...


Meaning, all the politics, hatered, war in this world will always continue you need not heed them and instead you should work towards your own salvation...
"The affairs of the world will go on forever. Do not delay the
  practice of meditation." - Milarepa
