World is a Mirror

Once the disciples of Guru Dronacharya asked him, "How is that Yudhishtra is recognized as an embodiment of virtues and Duryodhana as a wicked man?" Guru Ji did not give any answer. Instead He called out Duryodhana and said, "O Duryodhana, go and seek a virtuous man". Obeying his Guru's command, Duryodhana traveled far and wide and returned after a long time. He told Dronacharya: "I searched high and low but could not find even a single virtuous man in the whole world. I saw men only of evil nature everywhere."

Dronacharya then instructed Yudhishtra: "O Yudhishtra, find a wicked man and bring him to me. "Yudhishtra, too, traveled far and wide and came back after many years.  

Humbly, he approached his Guru Drona and said: "My worthy Master, I tried hard to find such a man but could not find even a single wicked man in the whole world." ​

Guru Ji then said “My dear disciples! Here is the answer of your question. You see the world the way you are. Most of the time we receive what we give and we perceive as we are. If we have a positive attitude we find that everyone is wonderful. And if we treat people with respect we receive respect in return.”  ​
One sees a reflection of his own mental disposition in others.It is a proof that there is no good or evil in this world. If you see evil in the world that means that evil is in your heart. So, this is a good indication of what you should change in your own life.
