What is the nature of impermanence, desire and anatman? If everything in unstable, unsatisfying and out of control then what is the point in living? Isn't the 'point of life' meant to be a journey to stability, satisfaction and self control? Thanks :).

  satisfaction and self control?


There's no "meant to be" in life. It's not written in the stars that you must do this or that. But you can follow the noble 8 fold path and attain stability and satisfaction while you live.


  If everything in unstable, unsatisfying and out of control


Everything is uncontrollable, but not unstable and unsatisfying. Only conditioned things are unstable and unsatisfying.
