I've been trying to find some info on meditation outdoors here. But I don't. My reason for asking is that I like, as far as possible, to sit outside in meditation. In my country, Norway, there's a lot of forest in the vicinity, even in the cities. And as I understand, Siddhatta Gotama and his followers were were also (at least outside the Rains) sitting outside.
A forest is never quiet. You notice that when you are quiet. And it's not "neat and clean" (When instructors talk about places for meditation, they usually say the place should be neat and clean). A forest is usually pretty noisy, uneven and unruly. It's full of stuff, sounds, insects, and animals. But for me this is not disturbing, sounds, (human) animals and "stuff" is more disturbing inside. This might be because I've always felt peace and ease in the forest.
So I'd like to hear from you more experienced people if some of you have been doing any meditation outdoors and what your experiences and advices would be.
