"What a jerk! He's always getting away with something, and her, what a gossip. You can't tell her anything unless you want the whole world to know it. They're so arrogant and pompous. What a pair!"
"Look at that big boat they just got. How can they afford it with the two trips they already took this year? I heard he lost money in his business last year".
Mmm. Have you ever found yourself talking about someone in a negative way? Of course you have. We have all done it at one time or another. But what are we really saying? In "The Work" that Byron Katie uses there is the turnaround question. In it you are asked to replace yourself with whomever you are speaking about. It's not easy. It's not pretty. But, it is probably true that what you dislike and/or envy in another person is what you don't like about yourself or an item or quality you wish you had. It's called looking in the mirror. A mirror is a reflection of your physical self but in this case it is a reflection of your inner self.
I highly recommend the book, "Loving What Is" by Byron Katie. This is but a speck of what The Work is all about. There are four questions in the book to ask you along with examples of how others used the model. I call it self-awareness therapy.
