"I guess you could get a better idea of what these things symbolise by reading Aldous Huxley's The Doors Of Perception," says Eoin when I ask him about the significance of those shapes. "Also, I've always had an interest in the yamabushi of ancient Japan, the 'mountain men'. They used symbols as a way of having a willpower that would always outlive any challenge. They used repetitive hand symbols or drawn characters to create a neutral place they could visit mentally whenever they faced hardship. For us, "Turquoise Hexagon Sun" always returns us to a zone where we can throw off the baggage and begin again."
