"La creencia en una única verdad es la causa raíz de todo el mal en el mundo."

Simplified Meaning:

When people are convinced there is only one correct way to think, live, or believe, it often leads to conflicts and problems. This idea can make people intolerant and close-minded, causing them to reject or fight against different viewpoints. For example, throughout history, many wars were started because one group believed their religion or ideology was the only truth and tried to force others to accept it. This mindset can lead to violence, discrimination, and suffering. To avoid these issues, it's important to be open to various perspectives and understand that other people can have different, yet valid, ways of seeing the world. By accepting diversity in thoughts and beliefs, people can live together more peacefully and respectfully.
