Attachment is the loss of freedom . . .
Non-attachment is freedom . . .
Our destiny is to be free.
~ by Maitreya
The only sufficient answer is to give up the animosity and try forgiveness, to try to love our enemies and to talk to them and (if we pray) to pray for them. If we can't do any of that, then we must begin again by trying to imagine our enemies' children who, like our children, are in mortal danger because of enmity that they did not cause.
