As I watched from my seat in a crowded community center, five men and women, one after another, were learning freedom through the very thoughts that had caused their suffering, thoughts such as “My husband betrayed me" or “My mother doesn't love me enough.” Simply by asking four questions and listening to the answers they found inside themselves, these people were opening their minds to profound, spacious, and life-transforming insights. I saw a man who had been suffering for decades from anger and resentment toward his alcoholic father light up before my eyes within forty-five minutes. I saw a woman who had been almost too frightened to speak, because she had just found out that her cancer was spreading, end the session in a glow of understanding and acceptance. Three out of the five people had never done The Work before, yet the process didn't seem to be more difficult for them than it was for the other two, nor were their realizations any less profound. They all began by realizing a truth so basic that it is usually invisible: the fact that (in the words of the Greek philosopher Epictetus) “we are disturbed not by what happens to us, but by our thoughts about what happens.” As soon as they grasped that truth, their whole understanding changed.
