In Tsawalk, hereditary chief Umeek develops a theory of "Tsawalk," meaning "one," that views the nature of existence as an integrated and orderly whole, and thereby recognizes the intrinsic relationship between the physical and spiritual. Umeek demonstrates how Tsawalk provides a viable theoretical alternative that both complements and expands the view of reality presented by Western science. Tsawalk, he argues, allows both Western and indigenous views to be combined in order to advance our understanding of the universe. In addition, he shows how various fundamental aspects of Nuu-chah-nulth society are based upon Tsawalk, and what implications it has today for both Native and non-Native peoples.
