In October, I sat inside James Turrell’s installation Hind Sight for the first time. This is what it was like: I followed a railing along a winding pathway before arriving at a chair, where I sat. I then stared across the room at something imperceptible: something made out of light, something not designed to be perceived by human eyes under normal light. I left the room with a greater understanding of friends and family who have had genuinely religious experiences. In Hind Sight, there was the sense of perceiving something utterly ineffable and yet utterly present.
