There is a place in pain, like in yoga or running, where to really get through it you have to go deep into your body. You must let go of thought, worry, fear and questions.
You must simple feel.
Feel the flow. The flow of each breath spreading through your body, bringing the same practiced feeling.
Be it Sun A or a 5k or, like me now, laid out and unable to move due to pain and spasms, you simply let go.
Breath becomes the meditation. Your only reality is this present moment. You can do nothing but focus on the sensations of your physical being. The flow of air in and out of your lungs, blood pumping in your chest, the burn as your nerves report back to base.
And so you breathe.
Because you can do nothing else.
And if you stop, there will never be another moment where you remember there is something else to life besides breathing.
So you take a breath in and out, then another. And you wait.
Because the present always becomes the past.
Breathe in, breathe out.
