"Navajo teachings provide a classic study of a land-based religion that involves every aspect of the physical world in a spiritual universe. Nothing is too big or small—everything holds a power, provides a teaching, and responds through an inner form. Beyond the material life of daily existence, there lies a world of interconnected relations made apparent in Volume II, The Natural World. This book graphically describes elements of life rooted in the Navajo philosophy of hózhǫ́. A unified harmony results. I highly recommend this book as a study in understanding the power of relationships that populate the Diné worldview."
—Clayton Long, a participant/creator of the Navajo Rosetta Stone; Bilingual Education Director (retired), San Juan School District, Utah; and curriculum developer for the Navajo Nation.

"For days after reading The Natural World, I found myself looking at my surroundings in a different way. The vibrant spirit of the earth and every plant or animal I encountered seemed to glow through a translucent shell. I have always been a nature-lover and gotten a sense of peace from being outdoors, but since reading these beautiful Navajo teachings I am filled with a profound sense of joy and gratitude every time I walk outside."
—Cindy Yurth, The Navajo Times
