Some wonderful practical experiences:
You can recognize from all kinds of different things that the Peace Network has indeed strengthened your home:
if you feel that you are being welcomed warmly when you return home;
the canary that is no longer moulting continuously and has started singing again;
a candy tin that doesn't empty so quickly anymore;
housemates who no longer argue with each other so often;
no longer have the urge to move;
babies who no longer cry all night and sleep through the night;
houseplants that will do better and flower bouquets that will last longer;
you will have energy left over for things you haven't had the energy for in ages;
...
...
and so it is.
