Sit, or lay down with your back straight. Or you can do it while you go for a walk, as you prefer.
Become aware of your body and your breath. Breath in through your nose.
If you get distracted, dont get mad at yourself, or fight against your thoughts, just let them be. Your thoughts will always be there, now you are just allowing yourself to distance yourself from them. Accept them with love, and come back to your body and breath.
It's a powerful way to become present, mindful, and come back to yourself.
