David Bowie's final music video for 'Lazarus' contains hidden references about his Kabbalah beliefs.
The 'Space Oddity' singer - who died on January 10 after losing his battle with terminal liver cancer - released the video before his death and according to a source the clip had a hidden message about the religion which is a branch of Judaism.
In the video, Bowie wears a striped top that resembles the one he wore on the album cover for his 1976 LP 'Station To Station'.
The image was taken by photographer Steve Schapiro, who did a photo shoot with Bowie in the outfit using chalk to do an outline of the kabbalistic tree of life, which is a classic descriptive term for the central mystical symbol used in the Kabbalah of esoteric Judaism.
And as he wears what looks like a replica in 'Lazarus' it might mean the legendary musician could have been "exploring" his past beliefs in the lead up to his death.
A source said: "There is absolutely no doubt this is a reference to that particular time in his life. David may have been looking into and exploring certain aspects of Kabbalah towards the end.
"The fact this is the last image of him on video - and this is the outfit he was wearing - is surely significant."
However, biographer Paul Trynka thinks his message about Kabbalah was "intended" but is not the whole message.
He told the Daily Mirror newspaper: "Right around the time of 'Station to Station', David started wearing a crucifix, naming it as a treasured possession.
"David often mentioned spiritual leanings, both Christian and Buddhist, but my take is he didn't endorse one particular religion exclusively.
"My guess is he was exploring the concept of death, the end of existence, rather than looking for a last-minute salvation."
