The usual Dakota version begins with the line "Hanhepi wakan kin!"

It is in at least two hymnals, "Okodakiciye Wakan Odowan Qa Okna Ahiyayapi Kta Ho Kin/Hymnal with Tunes and Chants According to the Use of the Episcopal Church in the Missions among the Dakotas" (hymn #15) and "Wakan Cekiye Odowan: Hymns in Dakota and English for use in Niobrara Deanery", also hymn #15. Unfortunately, I don't have those hymnals and thus can't type you out the rest of the text.
