[The ego] cannot tell the difference between an event and its reaction to that event. Every ego is a matter of selective perception and distorted interpretation. Only through awareness—not through thinking—can you differentiate between fact and opinion. Only through awareness are you able to see: There is the situation and here is the anger I feel about it, and then realize there are other ways of approaching the situation, other ways of seeing it and dealing with it.

Eckhart Tolle

from A New Earth: Awakening to Your Life's Purpose
