The symbol is a unalome, a representation of the journey to reach enlightenment. The path starts in the centre of the spiral, and as you continue up or down this path you are wandering, becoming more conscious of your surroundings.
Unalome tattoos are first spiritual symbols. In Buddhism, they ar e the visual image of reaching enlightnment. The spiral means our struggle with life, while the straight line shows that we have finally found harmony.
