Dependency and Suffering
Main reason of suffering is your Dependency, be it Physical, Emotional, Financial, Work or any other social dependency. The moment you start treating yourself like an individual and detach yourself there wont be any more suffering. You will be the Most happiest person on this earth. Though saying is always easy than actual doing as we are bound by our family (Brothers / Sisters / Parents etc), social (Friends ..etc) and Work related (Employer / Employees / Collegues ..etc) people. From my yest. experience i realized that People are angry when their expectations are not met. Your anger leads to frustration, you start feeling helpless and thus start suffering. Expectations are nothing more than depending on someone else. So if we dont depend on others than most of our sufferings will end.
