Pronunciation: Mee-tah-koo-yay Oy-yah-seen
Meaning: Mitakuye Oyasin is a Lakota Sioux term literally translated as: “All My Relations.” The meaning, however, extends beyond that of the English translation to include not only human family, but all of the animal, plant and mineral kingdoms as well as the forces of nature (wind, thunder, lightening, etc.) plus the elements, in that we are all connected in the intricate web of existence, and that each is affected by actions of any other. Everything is interrelated —nothing exists in isolation.
The very finest discussion of this concept I’ve come across is in an article written and copyrighted by Thomas James Martin, dated October 2, 2001. You can read it here.
