WHen I first saw the bird in the finale of BSG it made me think of The Guf and the movie “The Seventh Sign.” In the Talmud, the story goes that the Guf is the Hall of Souls. Every soul is unique and has its own purpose. The lore is sparrows, or some type of bird, can see the souls coming to and from heaven. It made me think of Starbuck and how she is some heavenly creature. She leaves the BSG world to be at her final destination.
In the movie “The Seventh SIgn,” Demi Moore is conviced that her unborn child is the last soul in the Guf(Which may or may not be true). The last soul leaving the Guf is the final sign that the Messiah is coming. The movie is a little freaky dealing with the seveth signs of the apocalpse. However, it is a good movie to watch and put in context with BSG.
