said the title of "Station to Station" does not refer so much to railway stations as to the Stations of the Cross, the series of 14 images depicting Christ's path to his crucifixion, each symbolising a stopping-point for prayer. He added it was about the Kabbalistic Tree of Life, evident in the line "from Kether to Malkuth", which bookend the Tree of Life: "so for me the whole album was symbolic and representative of the trip through the Tree of Life". Pegg believes the song displays a combination of Christian and Jewish allusions. The song refers to William Shakespeare's play The Tempest. Fixation with the occult was evident in such phrases as "white stains", the name of a book of poetry by Crowley. Cocaine is also referenced directly in the line: "It's not the side effects of the cocaine / I'm thinking that it must be love." Spitz interprets Station to Station as "an album of love songs", specifically "the kind you write when you have no love in your own life". Indeed, Perone considers "Golden Years" the type of love song that does not feature the word "love". The song's character assures his companion that he will always protect her no matter what and promises her a brighter future. Carr and Murray write it carries "an air of regret for missed opportunities and past pleasures". The lyrics of "Stay" have been interpreted as reflecting on "the uncertainty of sexual conquest", and as an example of "the Duke's spurious romanticism". Religious themes, as well as belief in spirituality, are prevalent on "Station to Station", "Word on a Wing", "Golden Years" and "TVC 15"; for Carr and Murray religion, like love, was simply another way for the Duke to "test his numbness". Bowie has claimed that on "Word on a Wing", at least, "the passion is genuine". There is a comedic flavour in "TVC 15", which multiple commentators describe as a "surreal comedy". It concerns a character's girlfriend being eaten by a television. The song was inspired by a dream of Iggy Pop's featuring a similar premise, as well as a scene in The Man Who Fell to Earth where Newton fills a room with television screens, each tuned to a different channel. Pegg calls it the album's "odd man out". Artwork and packaging The album cover is a black-and-white still frame from The Man Who Fell to Earth, in which
