Nothing outside can bring joy or sorrow , everything is seen as play in 5 dimensional movie happening around you every second of your waking state ,this same happen in your dream state till you reach your deep sleep state ,once you know this deep sleep state in your awakening state then one has actually reached his final abode.
As you achieve Deep Sleep state in your waking state ,then this physical world will have no power over you.
You are in your equilibrium state, zero state , fully contended as if universe is within you.
