A life that is lived without purpose or focus, the kind in which one never discovers the reason why one was born, is joyless and lacklustre. To simply live, eat, sleep and die without any real sense of purpose, surely represents a life pervaded by the life-state of Tranquillity or Animality.
On the other hand, to do, to create or to contribute something that benefits others, society or ourselves and to dedicate ourselves for as long as we live, to that challenge, is a life of true satisfaction, and more importantly, a life of value.
To live life with purpose through Buddhist principles is a humanistic and meritorious way to live, so don’t just sit there, get on with life !!!
