      Sand or dry painting is an art form developed by American Indian tribes in both complex and simple
manners. Despite that it is a type of art, it serves more of religious rather than aesthetic purposes because it is invariably linked with healing ceremonies during the rituals. As demonstrated in the religious ceremonies of American Indian tribes, sand painting often presents pictures with styles and symbols. Usually, pictures of deities, animals, lightning, rainbows, plants, and other symbols are drawn because these images are depicted in the chants that accompany various rites. As for the materials that have been used in sand painting, those include crushed and colored sandstones, charcoal, pollen, or other dry materials in various colors such as white,blue, yellow, black, and red.
      The way in which the American Indian tribes utilize sand painting for healing is not complex, but the
healing power of the sand is highly valued. There are mainly three stages to complete the whole process before,during and after the healing. First, a sand painting needs to be completed. That is to say, when a curer attempts to heal a patient, s/he often chooses what s/he wants to paint in order to achieve his/her task. Second, the healing will then commence. In other words, as soon as a healer completes his/her painting, s/he then asks the patient to sit on the center of the painting and applies the sand from the painting to parts of the patient’s body. Third, when the healing is accomplished, the painting still needs to be dealt with. That is, upon finishing this healing ritual, the painting has to be destroyed. Only when every stage of the whole process is fulfilled will the healing potential of the sand painting be enacted.
      Due to their respect for sand painting as a sacred and holy artifact, the Indians have forbidden the original and unchanging replication of sand painting. Even though the duplication is inevitable, they pay heed to ensure the authenticity of the original one. For instance, when the paintings were duplicated in rugs, a mistake was intentionally made so that the initial design would still be substantial. However, things have begun to change nowadays regarding this duplication issue. For the purpose of recording and conserving this highly esteemed art form that is of significance for the transmission of American Indian tribal cultures, many of the paintings have been copied and are no longer seen as something forbidden. Many artists around the world have all devoted themselves to promoting the aesthetic values of sand painting. More innovation has been added to the development of sand painting. With evolution and revolution constantly in progress, sand painting has transcended its original form.
