All the things you need will help you have a comfortable time. Spending time in a beautiful place, I always do the concentration on the inner feelings and perception of the present moment, to plunge into the atmosphere of the forest as much as possible it is necessary to connect all our senses.
Pay attention to:
Sound - howling wind, doldrums, rustling twigs, birdsong, creaking snow.
Smells - the freshness of winter, the smell of tea, fire.
Touch and sight - to touch and examine the bark of trees, branches, needles, leaves, frozen cereal flowers, snowflakes, snow, mosses and lichens, animal tracks.
To breathe deeply, enjoying this fragment of life.
