This is a beautiful poem with gorgeous imagery and great rhythm, especially in the last stanza. "I know the life in deadened lands" is just marvelous. A poem I think you should look up is "Breaths" by Birago Diop. It has some elements of nature-spirituality, but the imagery he uses is similar to yours. And by the way, you are not alone in hearing the laughter of the stillness :) If you would like, you can check out some of my poems; I feel the same way!

Thats a very good poem! I like it!
