Groping in the dark, through a narrow tunnel, 200 metres below earth. Knowing what’s ahead of you through precious touch – of a garment, a scrape of rough stone, a taste of raw salt. It’s an experience – a mix of excitement and novelty, and just a dash of fear. What if you can no longer touch anyone or anything but air? What if the murmur of excited voices that echo around you fade away and you find yourself all alone. But, luckily for you, some short moments later, there’s light at the end of the tunnel. Literally. Like you wished there to be light and there was light. And as you look behind into the gaping maws of darkness, you know that you would never again take Light, no matter how feeble, for granted.
