Writer and Ancestor worker Laura Patsouris was recently interviewed about ancestors, ancestor work, and indigeny. This is a wonderful and informative interview and I encourage people to set aside time to listen to it. Toward the end, Laura talks about indigeny and how, if you go back far enough, all of us come from indigenous cultures. She talks about the effects of conquest and how the ancestors can help every single person overcome.
