When Native Americans pray to the 4 directions it is a prayer to the spirits of the world, to life & the Great Spirit that encompasses the 4 directions & everything that is. The Medicine Wheel is a symbol that incorporates the 4 directions. Its spokes point east, south, west, & north. The 4 quarters are colored red, yellow, black, & white representing all races, seasons, & stages of life. The circle is the earth, moon & planets. It is the circle of life & all creation.
