How is terrapsychology different from native/aboriginal methods of tending the spirit of place?
Terrapsychology draws on some of those methods, and needs to because of the ancient wealth of wisdom they contain; but it also includes depth psychology, some psychohistory, ecology, and other contemporary disciplines. Also, native methods weren’t designed to deal with places as heavily wounded by colonization, pollution, warfare, etc. as those we now live in after centuries of conquest.
