A few from Black Elk
"The Great Spirit is everywhere; he hears whatever is in our minds and our hearts, and it is not necessary to speak to Him in a loud voice."
"Perhaps you have noticed that even in the slightest breeze you can hear the voice of the cottonwood tree; this we understand is its prayer to the Great Spirit, for not only men, but all things and all beings pray to Him continually in different ways."
"Grown men may learn from very little children, for the hearts of little children are pure, and, therefore, the Great Spirit may show to them many things which older people miss."
"Everything the Power of the World does is done in a circle. The sky is round, and I have heard that the earth is round like a ball, and so are all the stars. The wind, in its greatest power whirls. Birds make their nest in circles, for theirs is the same religion as ours. The sun comes forth and goes down again in a circle. The moon does the same and both are round. Even the seasons form a great circle in their changing, and always come back again to where they were. The life of a man is a circle from childhood to childhood, and so it is in everything where power moves. Our tepees were round like the nests of birds, and these were always set in a circle, the nation's hoop."
"The first peace, which is the most important, is that which comes within the souls of people when they realize their relationship, their oneness, with the universe and all its powers, and when they realize that at the center of the universe dwells Wakan-Tanka , and that this center is really everywhere, it is within each of us. This is the real peace, and the others are but reflections of this. The second peace is that which is made between two individuals, and the third is that which is made between two nations. But above all you should understand that there can never be peace between nations until there is known that true peace, which, as I have often said, is within the souls of men."
