A beatiful simple short story (or maybe legend or a fairytale - you choose) that shows us the way we behave and act and on the other hand the way we want to behave and act. Obviously, these are not the same ways and most of the times they are very far one from another.
The prayer, simple as it is, shoukd be seen in every action we make during our life. But sadly, it is not shown. Not even a little bit.
In the book we see the way the shepherd makes, with his companions, to finaly see the light. They meet people on their way (good and evil) that teaches them (everyone in his own way) a lesson for life.
Eventualy, it is our own choice the way we act. We could be evil or we could be good. It's only our choice...
