Floral Om Symbol Men's T-Shirt. The Om symbol has been adopted by yogic practitioners, spiritual healers, new age hippies, psychedelic rock groups and even pagans. Its roots lay in Hinduism and it dates back millennia. It's meaning is both specific and ambiguous, which is why it's proved so popular outside of its Hindu origins. This Men's Om T shirt is an ideal gift to your self or a friend/relative, with the Om (or Aum) symbol itself formed from hundreds of tiny colourful flowers.
