An icebreaker
As Lakota teachers hold it, Wakȟáŋ Tȟáŋka names the sacred itself — not a single god like the English phrase 'Great Spirit' suggests, but something closer to Great Mystery, encompassing many sacred powers at once. No English word fully carries it.
Working as reservation physician from 1896 to 1914, he recorded elders describing Wakȟáŋ Tȟáŋka as sixteen related sacred powers rather than a single god. He credited his named informants directly in his published notes.
He has argued that 'Great Spirit' is a Christian-influenced mistranslation that misrepresents the term, and that something closer to 'Great Mystery' better carries its sense of an all-encompassing sacred power. His scholarship draws on decades of work with Lakota sources.
He argued that anthropologists and missionaries routinely flattened Indigenous sacred concepts into Christian categories that didn't fit, distorting terms like this one in the process. He called for Native intellectual traditions to be taken seriously on their own terms.
He taught that many Lakota spiritual terms, including this one, have no real English equivalent and lose meaning the moment they're forced into one. He urged students to learn the language itself rather than rely on translation.
