Imagine tramping through a forest on a fine day, enjoying the air and exercise. Suddenly, inspired by the trees, you stop and simply stand. Gradually the signs of life your coarse trespass has scattered would start to reappear. Birds singing, birds sighted, rodents rustling in the undergrowth, squirrels and maybe a marten in the trees. This is meditation. You stop and simply pay attention, and slowly realise there's far more present than you could ever have imagined.
