The strength that comes from the soul

 
One day two young soldiers came to the bird - keeper of the Black Stone with a request to increase their knowledge of the arts of war and explain to them how to manifest the power that comes from the soul. Bird boys listened and asked one of them vastly superior physical strength of his friend, to show the power of the body and raise the huge stone lying nearby. When a warrior barely picked up a stone, Bird asked him if he could throw his burden away from themselves.
- No, I can not - honestly one.
- Then put a stone on the leg of his friend - asked Stone Bird.
No sooner had the strong warrior fulfill orders Keeper of the Black Stone as his friend, suddenly cried out, grabbed a chunk and threw it away from him.
- That is the power that comes from the soul, - said the bird - and it depends only on the desire of the soul itself.
