As the song says
 
"When youre weary, feeling small, when tears are in your eyes"
 
When you find it hard to take one further step. 
When life assaults you and you feel ashamed, guilty and beaten.
When everything that happens to you seems to have meanings and implications that grow arms and legs.
When you feel alone and unsure of yourself.
 
Let the ancient story of Robert the Bruce lighten your load and set you on the road to healing.
