Thing is not the real nature of all things... it is only the appearance outside; IT IS ILLUSION.
Birth and Death also are the illusion, they are in the process of change or becoming...
Everything is just an illusion... so why we are so much worry about all things???
What is, is. What is not, is not.
So...
We have to learn how to "Let it go".
as the story told...
It is as if we are carrying a big stone. It is heavy to carry. However we don’t know what to do with it. Therefore we keep on carrying it. And when somebody asked why we don’t throw it way, then we started to think that if we throw it away, then we would have nothing left. Until we are very exhausted, until we can no longer carry it. And let it go.
When we let it fall down, we would learn a lesson of “letting go”. We will be relieved and be aware of how heavy the stone was. When we carrying it, we just don’t aware of the benefit of letting go.
