Have you ever tried to talk to a tree? I don't mean you have to walk up and open your mouth and start speaking, although that is certainly one way of doing it. I mean pausing, directly your full attention to that tree, opening up your consciousness and sending out a friendly intention. A silent "hello" or a "virtual wave" if you will, an acknowledgement that before you is a living being with its own spirit and awareness, that rejoices in sunshine and soaks up the rain waters, that is a living part of this planet.
The first time that one talks back, it will change your life... if you let it.
