Byron Katie said this quote

All I have is all I need and all I need is all I have in this moment.

~ Byron Katie

A thought is harmless unless we believe it. It’s not our thoughts, but our attachment to our thoughts, that causes suffering. Attaching to a thought means believing that it’s true, without inquiring. A belief is a thought that we’ve been attaching to, often for years.

~ Byron Katie

The only way I can be angry at you is when I have thought, said, or done something that is unkind in my own opinion.

~ Byron Katie

Since the beginning of time, people have been trying to change the world so that they can be happy. This hasn’t ever worked, because it approaches the problem backward. What The Work gives us is a way to change the projector—mind—rather than the projected. It’s like when there’s a piece of lint on a projector’s lens. We think there’s a flaw on the screen, and we try to change this person and that person, whomever the flaw appears on next. But it’s futile to try to change the projected images. Once we realize where the lint is, we can clear the lens itself. This is the end of suffering, and the beginning of a little joy in paradise.

~ Byron Katie
