Thinking that things should be other than what they are is opposing reality.
It’s a war with reality.
It’s arguing with reality, as Byron Katie says.
To think things should be a certain way feels terrible.
It feels terrible because the reality is as it is whether you like it or not.
It feels terrible because we’re out of alignment with what is.
It’s like shouting at a tree that it should be a flower.
It remains a tree, no matter how strongly you believe it should be otherwise.
How does it feel to think things should be a certain way?
What would feel better?
