Thought is a formidable power.
But speech, the outward and physical form of thought, is even more so according to the Navajo belief. The evocative power of speech, through songs, chants, and prayers, allows their thoughts to be realized or materialized. It is an authentic means to an end. Like the world itself, Navajo chants and songs are perpetually evolving. As they are orally passed from one person to the next, they change and develop.
