I am beside you
Look for me
Taken on their own, the lyrics for "Ghosteen Speaks" are quite opaque. Luckily, Cave has spoken pretty openly about what they mean. In issue 103 of The Red Hand Files
, he went into the topic while answering a fan's question about the song.
He explained that Ghosteen is the "invisible, migratory... spirit of love" and is the person speaking through Cave in the song (as opposed to Cave speaking as himself).
Ghosteen "calls on the compassionate act of witnessing - seeing," Cave explains before going into an analysis of love as a form of acknowledging someone's existence, particularly powerful when applied to those who feel invisible in their lives. The humble recognition of another person's being there, in Cave's view, is an act of love and an act of service.
Cave has called the first eight tracks on this album "the children" (with the last three songs being "the parents"). That makes "Ghosteen Speaks" one of the children, as it's the seventh track.
