This picture amazingly captures the think layer of clouds within the valley near the south of Lake Como, northern Italy. In the above image, the dense cloud hides almost the valley and instead gives off some artificial lights which make the city like an opaque blanket. The village over distance is clearly seen from the blanket. Long before there was machines to sort out on and competitive sports to keep us moving and before wars were being fought, man didn't think about fitness and health as a technique of keeping healthy. He simply knew that if he didn't hunt, he wouldn't eat of course, if he didn't run, something would hunt him. They were challenging times that focused simply on survival. Before going into battle a soldier needs to prepare. To wear the proper armour and get hold of a shield and sword. The armour protects from harm as well as the sword kills the not so good guy. You also have to be fighting fit. It's the same if you battle against yourself. You need protection from dangerous illusions and also to be equipped with right knowledge and understanding.
