If I let myself succumb to the fear that would lead to fear and anger and hatred, not only planes were hijacked that day but my life [would] be added to that list of casualties.

Afflictive emotions - our jealousy, anger, hatred, fear - can be put to an end. When you realize that these emotions are only temporary, that they always pass on like clouds in the sky, you also realize they can ultimately be abandoned.

Hatred is settled anger

His anger took many shapes: sometimes soft and familiar, like a round stone he had caressed for so long that is was perfectly smooth and polished; sometimes it was thin and sharp like a blade that could slice through anything; sometimes it had the form of a star, radiating his hatred in all directions, leaving him numb and empty inside.

But you can only go so long being angry before you learn to hate.

Anger, used, does not destroy. Hatred does.
