Let’s say you break your leg. Your first reaction is usually “HOLY FUCK FUCK FUCK THAT HURTS” and your mind will do anything to try to escape it. But if you turn your attention towards it and focus on it directly, you can start to slightly diminish it by picking it apart. Is it a throbby or stabby pain? Is there an underlying itchy sensation? If you accept the pain and embrace it, it helps reduce it by seeing it for what it is and, more importantly, is not: You are not dying, even though your brain is reacting like you are.
The Buddhist mindset is kind of like that, but for all of your reality. The zen doesn’t come from running away, it comes from seeing and accepting everything as it is and understanding that the only thing you can control is your mind’s reaction to it.
