The ankh, or Egyptian cross, is a symbol of eternal life. Egyptians often associated it to sun and water, both necessary to life. Some theories compare the upper circle to the sun disc, and consider the lower "T" as being representative of the river Nile, the source of life, with the horizontal line being the edge of the world, both material and spiritual. Hence the idea of the Nile as a path between the worlds of the living and of the dead.
Wings symbolize freedom, and fire symbolizes change, transformation.
