According to Davey Ray Moor's Songfacts interview
, "'The Innermost Light' was written with Carl Barât from The Libertines. He turned up for a songwriting session with that phrase. Carl borrowed it from a tattoo on his manager's arm that quoted Aleister Crowley, the Edwardian occultist of Led Zeppelin renown. Crowley used 'The Innermost Light' as a term to describe what others might call 'the soul,' or the inner spark of light that is our thoughts. Carl and I worked around ideas of light, and the quest for the innermost light in the eyes of a soulmate."
