Part 1
Blaming others for the pain we feel each time someone fails to live up to our expectations is no different than burning our tongue on coffee that's too hot to swallow, and then calling our cup an idiot!
Part 2
What we should seek in life is clarity, not comfort, for what is made clear becomes pure. Such purity is the heart of peace, while those parts of us that search out ways to comfort our pain keep us in the conflict of serving two masters: the suffering we fear and a pleasure-born peace that always fades away, leaving us to run after it.
