The quote that supports the analysis of the Kiowa's belief in the power of language is the following:
"Even now when they see the storm clouds gathering, the Kiowas know what it is: that a strange wild animal roams on the sky. ...But they speak to it, say "Pass over me." They are not afraid of Man-Ka-ih, for it understands their language."
This quote clearly states the importance of storytelling and how it was a tool of Kiowa survival, this quote shows hos they acted upon the world, in this case, upon a natural phenomenon, through language.
