One of my favorite nondual teachers is Byron Katie.
A lot of people don't think of Byron Katie as a nondual teacher, and that's one of the reasons her work is so powerful.
The first question that she asks a student who's struggling is "Is it true?" And the second she asks is "Is it really true?"
Is it really true that your brother hates you? Is it really true that you should have a better job? Is it really true that your relationship is a mess?
Bryon Katie helps people find that there are other truths that are just as powerful.
Maybe I hate my brother, and not the other way around.
Maybe my relationship isn't a mess. Maybe I am.
Every thought expresses a point of view, and most often, we just look for evidence to prove the stories we tell about ourselves. And we ignore things that might fly in the face of those stories.
But the truth is seldom that convenient, or simple. The truth can be harsh, even cruel, but it can also be our best teacher.
