Man, that one has been an elusive thing to find.
For me, I have only been able to find peace when I accept things the way they are.
Sure, I can work to change them, but the first step is acceptance.
I find this view is enough to bring about "Peace".
I absolutely agree Laura ... it starts with acceptance and ends with precious experience.
"We cannot change anything until we accept it. Condemnation does not liberate, it oppresses."
--C. G. Jung
