One thing that you find out

"One thing that you find out when you have been practising mindfulness for a while is that nothing is quite as simple as it appears. This is as true for walking as it is for anything else. For one thing, we carry our mind around with us when we walk, so we are usually absorbed in our own thoughts to one extent or another. We are hardly ever just walking, even when we are just going out for a walk. Walking meditation involves intentionally attending to the experience of walking itself. This brings your attention to the actual experience of walking as you are doing it, focusing on the sensations in your feet and legs, feeling your whole body moving. You can also integrate awareness of your breathing with the experience."
