This spiritual meditation on liberation, light and freedom, was written by the band's principal songwriter Martin Gore. Frontman Dave Gahan told The Guardian March 21, 2009: "It was called Footprint to start with but then it changed. Martin does that. He's very particular about his song titles. At the last minute he'll change the title and he worries I think if there's another song with the same name."
Gore told Billboard magazine that he considers this song and "Peace" to be the core tracks of Sounds of the Universe. He explained: "I wrote them back to back, and the flow of the album started to make more sense. I really felt they had a spirituality to them. That somehow set a cornerstone for the rest of the writing."
