The Buddha says:
Everything is created and controlled by the mind.
If we do or say things with the wrong attitude,
suffering will follow us just like a cart follows the ox.
Your mind is like a mirror—it reflects the world around you. However, if the mirror is covered by dust, you won’t be able to see anything. If you want to be wise and perceptive, your mind must be free of the worries caused by conflicts with others.
There is an old saying: “Those who are involved are confused, while the bystanders see clearly.”
