The Dalai Lama, I think, said that..
That not getting what you want sometimes is a wonderful stroke of good luck..
I think once we understand that.. Our shoulders relax, one can feel the muscles relax and let go, and all that stress hidden unknown within us seeps out..
What clinches it is that .. When we truly let go and make peace with it ..
We get what we need.
Need. Not want. And what else could we ask for but to be taken care of?
