What do you value? What is it you work to attain or maintain? Let go your attachment to that now. Whatever you desire, whatever you believe should be the outcome or reward of some effort, even if that effort be love and the results seem to be for the highest good; it is made of the stuff that is the source of all suffering.
All disappointments and struggles are all the result of holding a standard, and having values that must be met. Unfulfilled, these establish and make manifest suffering. Accomplished they bring along the suffering of worry that they may not remain. It can be no other way. Let go your attachment to all three: attain, maintain, retain, and you will know the only thing that is real and permanent.
