When a person hears the word mediation, generally one thinks of calming the mind while seated inside a comfortable room with their eyes closed.  Though I have meditated in this manner many times, I find the best form of mediation cannot be found inside a comfortable room, but instead by going outdoors. 

Behind my home is a small valley.  When I walk in the valley everyday life disappears beyond the surrounding hills.  The walk is as calming as any seated meditation.  When I sit on the ground in this area and close my eyes, I feel a stronger connection to the energy so many refer to as God or Source than I ever feel indoors.

If you commonly meditate inside, do a test and go outside for a few days and meditate.  You must necessarily set aside your fear of spiders and other insects.  I understand this can be tough.  But when you do, you will feel the wind and sun on your face, smell the air, feel the texture of the ground, and you will feel your mind calm in the solitude.  Try it out.
