"I'm still learning about Alice Coltrane; I can't really claim to know a lot about her. I've heard a lot of music from her - she did a lot of different things - but this is the first of hers that I really listened to. The first time I heard her, I was performing on this all-night radio show in LA and it took place in a church. After I'd performed, I lay down on this pew to sleep and the DJ played this record and I woke up and it just really hit me. It was the track 'Yamuna Tira Vihari' and I was like, ""Oh my god"". It was so immersive and a flood of light, and so ecstatic. I can hardly explain. I was delirious, almost. There were all these strings and an organ, I think, and then her voice chanting and it's so insane. I listen to it a lot. It's spiritual, I think - and I don't know anything about that aspect of it - but I listen to a lot of music in that way. I listen to a lot of early music and Renaissance music, a lot of choral stuff. You know that this is a spiritual record and you almost don't need to know about that aspect of it. It just gets you. But I think that's okay, I think you can do that."

"Directed by the Danish master Carl Theodor Dreyer, Ordet is yet another film made in 1955 to which I’m deeply indebted. There is a stunning scene of literal resurrection that inspired my own visual approach to The Exorcist and gave me the courage to stage a supernatural event as if it were actually happening, without scary lighting or weird angles. Like many of Dreyer’s other films, including Vampyr and The Passion of Joan of Arc, Ordet is based on literary source material (in this case, a play). But all his films are deeply spiritual in their examinations of the mystery of faith, and purely cinematic."

"This is one of my favorite science fiction films ever. It feels like everything in Solaris is transcendent and so deep. It’s hypnotic. It has so many sequences that are unique and unforgettable, like the part where the characters float in the library or when the wife comes back to life and then breaks apart as if she were made of glass. And there’s the idea of this spaceship floating on top of a strange ocean that seems to have some form of consciousness. All of those ideas are so strange and beautiful. It’s remarkable that Tarkovsky was able to make a film this spiritual in the Communist era. I don’t know how he did it."

"Alan Lomax was a folklorist and ethnomusicologist who was making archival recordings and field recordings in the 40s, and this album consists mainly of prison chain gang songs. The first time I heard it, it stopped me in my tracks - it was incredibly moving to hear because it's just the sound of male voices and pickaxes and nothing else... it sounds haunted but hopeful. Like listening to ghosts, the quality of the singing and the recording [is such] that you can never have again - a document of its time. It's spiritual: the pain is in their singing, which would have been their only mode of expression. It's singular and not something I'd put on everyday, being a heavy listen."

"It’s a film like the other two, in a way, which has grown as I’ve grown; it’s changed with me. You think of films as being finished, completed things that never change, but actually they do change — because we change. And so a film like Close Encounters, when I first watched it — when I was much younger — it scared me to death, and now it’s a film that I find intensely moving. It’s an almost spiritual film. Spielberg is just, I think, a genius in being able to tell a very simple story and get to something so complex and profound. I think he does in E.T. as well, to a certain extent, but this one I find one of the most moving films I’ve ever seen."
