Once upon a time, in a small village with low houses and colorful yards, there lived a dog with a strong body and a sharp gaze. He was a vigilant guardian. All day long he stood outside his master's house and did his job well. No one dared to enter without permission.
But he had one bad trait. When he entered the house, jealousy and stubbornness awoke within him. He could not stand seeing the man move freely, sit, eat, and do whatever he wished. Then his malice flared up, not because he had been hurt but because that was simply his nature. He growled softly and sprang to bite his owner as if he wanted to prove that he was the strong one in the house.
The man was frightened. He tried to talk to the animal, to calm it, but it was no use. Every time the door opened, the same thing happened. So at some point he decided to keep the dog outside, where the animal showed discipline and did not let its malice appear.
To protect others as well, he put a muzzle on him, not out of revenge but out of necessity. The dog became angry. His pride was wounded. He could not bear the idea of being held back and made weak.
One night, he decided to leave. He crossed the fields, entered the forests, and began to wander. His malice no longer had a target, but it was still inside him. He tried to overcome it. To make himself stronger, he struck his body against the tree trunks as if training himself to gain the endurance of a bull. But the more he did it, the more he realized that all this effort brought him no meaning.
And so the dog continues to wander through the fields and the forests, alone, carrying within him the same malice that drove him from the house. He strikes his body against the trunks to prove to himself that he has gained the endurance of a bull, but every effort ends up useless. For no matter how strong his body becomes, his heart does not change and there lies the weight he cannot cast off.
