Several years ago, I remember talking about the nature of thought with a guest at the homeless shelter.
I was pointing to the concept of being aware that thought/feeling can be like the "check engine" warning light in our car. If
any thinking/feeling comes with a bad feeling, it's a potential warning light to us that our state of mind and our thoughts are (in that moment) not that clear or helpful to us... and if we somehow become aware of that, we may get some common sense and clearer
thinking in how to best navigate our response to that momentary experience.
