When we're angry, we are filled with rage at the world as it appears to us. We are inflamed with a burning issue that cannot be resolved with the world as is. We are on fire with desire for a different world to live in.
Where we go wrong is to take "the world" literally. We think, incorrectly, that the world to fix is the one on the outside. We assume there is only one real world and our five senses tell us the truth about that. We dismiss our inner world as mere mind stuff, worries and unreliable moods.
When we've spent lots of time in reflective practice, we get a different sense of our inner lives. The world inside becomes equally real to the outside one. At some point it becomes the only world that's real. It appears as consciousness to us that cannot be born or die, only continue eternally.
Once we've realized how our inner world is partly or totally real, we are seeing double. When we get angry we have a new place to go. We can consider how to change the world of our beliefs. We get that the world as it appears outside us is a representation of the world we believe in deeply.
The world we can change within us is comprised of our 'facts of life". We believe in what cannot be changed by us. We assume certain rules are the way the world works for us, our particular fate, and how we've been cursed or blessed in this life.
We've learned this inner world by experience. We've graduated from the school of hard knocks. Life has taught us how to limit ourselves, fear for our survival, join in consensual anxieties and feel guilty about our happiness.
This belief system works like film in a movie projector. It creates appearances that reflect, validate and perpetuate the recorded assumptions. It sends out signs of what is believed so deeply it appears as unchangeable facts of life.
This is the world we are on fire to change when we get angry. If we are seeing double, we know which world to change, and which will happen to change on its own when we succeed at the inner transformation.
