Mindfulness allows you.
To create just enough mental distance from thoughts to see them as such.
To shift your perspective on your thoughts. To let you see they are just thoughts, not reality.
To help you understand you do not have to believe your thoughts.
Without holding a mindful stance.
To recognize thoughts as mere thoughts.
Seeing them as well-worn ruts in the mind: “Oh, I’m having those thoughts again.
Thoughts like you’re worthless; it’s hopeless; your life is futile can run on and on.
Don’t you want to stay active and mentally alert?
With your inner radar attuned to detect and challenge such thoughts?
Rather than simply letting them run on and on?
