Geometric Arrow. I found the basic design on Pinterest and then added my own flair to it to fit me. The triangles in the middle of the shaft represent the four elements: Air, Fire, Water, and Earth, respectively. The eight-spoked circle in the center represents the Wheel of Life. The arrow itself represents how an arrow can only be shot forward by being pulled back, so that in life, you must remember that you sometimes have to go backward to go forward again. For my left inner forearm.
