I intend to eventually do my meditation outdoors as much as possible, in a particular spot that has a metaphorical flashing neon sign on it that says "meditate here!" Do you think it would be better to do these exercises there, or to stay in the more controlled surroundings indoors until I have the techniques down? So far I've been doing about half and half; it hasn't made much difference for sitting motionless, but could the potential distractions of wind, weather, birds, insects and so forth become an issue down the road? Indoors, nothing in view moves.
