The loss of connection to plants, to the land, to Earth, leaves the holes with which we are naturally born unfilled. No matter how much Ritalin or Prozac is poured into those holes, synthetic pharmaceuticals can never fill them; merely human approaches can never heal them. Pathologies come from the empty holes that are unfilled, from lack of contact and communication with the wild. The holes within us possess particular shapes—that of stone or tree or bear. It is not only plants that are our teachers and healers; not only plants that are among our community of life; not only plants that have a language we have long known. — The Lost Language of Plants

This is so true. When you sit in the woods you become aware of some thing grand. The spiritual world is more clearly perceived, and a peace settles over you. This is missing from the world we have built where we are completely seperate from nature.
