There was once a heroic knight. His bravery was great, and his sword was feared, but he was tired of hunting for dragons, and other animals. He decided to abandon that life, and come and test out his bravery and skill in the real world.However, when he arrived here, he found no terrible creatures, no evil wizards, not even a poor stepmother to wave his sword at.It was very strange. All he saw were worried people, with the same looks on their faces as he had seen on the faces of people he was rescuing from dragons.It didn’t seem like there was anyone to put them in such fear, or to make them live in a state of such anxiety and sadness.But, at the end of the day, nothing really bad had ever happened. And so it was, day after day. The knight thought that maybe this could turn out to be his most heroic adventure ever, and he decided to totally devote himself to finding the source of this mysterious worry in the real world. He searched, he inquired, he investigated, he sailed, he climbed... but he found nothing.Not willing to give up, he returned to the fairytale world to speak to The Wise Old Man.”Tell me, wise one. What is the great invisible enemy that strikes fear into the hearts of people in the real world? I still haven’t found it, but I won’t rest until I have defeated whatever it is, and freed everyone. Just like I did here, for so many cities.”The Wise Old Man was quiet for a long while, then finally said: ”You have neither the strength nor courage to win this battle. The enemy does not exist, yet it is powerful, and as numerous as the stars in the sky.””What?!” protested the Knight, ”Is that even possible?””In the real world, because they have no dragons or ogres, they invent their enemies, and they carry them inside. Each person there has an enemy made to measure, which lives inside their heart. For some it is called greed, for others envy, for others selfishness, pessimism or desperation. They have sown the seeds of negativity in their souls, and take the fruits with them wherever they go. It is no easy task to uproot all that.”"I will do it,” answered the knight, ”I will set them free.”And so the knight returned to the real world, bringing all his weapons with him. Everyone he met, he would offer to free them from their negative inner life.Only you can fight that negative being in you that makes you do wrong.
