99.9% of our suffering is created by listening to what our mind is telling us. What our mind is telling us is an exaggeration and a misinterpretation of reality. It does this not because it’s diseased or damaged, it does this in a perverse way, to keep us safe. The only way we can mitigate the suffering created by our mind is if we take what it’s telling us and compare it to what reality is telling us. When you do that you will see two very different things.
Denial produces suffering because we refuse to see this distinction. It’s not that we can’t see the distinction because we can, it’s that we make the decision to pretend we don’t see it.
