In a comfortable position, let all tension in your body dissipate.
This exercise is a staple of mindfulness, designed to simply enhance your awareness of your own thought
Focus on your breathing first, then move your awareness to what it feels like to be in your body.
Finally move onto your thoughts
Be aware of what comes into your head
Remember to breath
Resist the urge to label or judge these thoughts.
Speed doesn't mean mastery here.
