The tattoo says ‘OM’. Om is a sacred monosyllable that symbolizes the oldest of Hindu mantras. The word refers to the sound of the past, the present and the future. The sound (aum) is composed of four parts; a, u, m, and the after sound of nasal humming. These 4 parts are compared to the four states of consciousness: waking, dreaming, sleeping and the transcendence of self beyond the mind.
