I (recently) watched the Battlestar Galactica TV series. It is steeped in religion and religious themes - the dialog and thoughts of characters, the objective events taking place, and the Colonists' and Cylons' culture and, well, religion as described in the series.
Now, I was quite impressed by the emotional resonance of the opening theme of the series; but only after I finished watching the entire thing did I take the time to try to figure out what language that was - only to discover that the theme is a rendition of the Gayatri mantra - a key Hindu-religion mantra originating in the Rig Veda, the thousands-of-years-old Hindu corpus of scripture (in the Sanskrit language).
Is this a significant part of the series' message? (I mean, the fact that it's a Vedic mantra; of course the words of the Mantra relate to the quest of the Colonial fleet throughout the series) Are the Cylons supposed to represent Hinduism, or Brahman, the monotheistic aspect of it? Perhaps it's the other way around, and the Colonists are like Hindus, worshiping many gods, with the Cylons bringing them the message of 'proper' Judeo-Christian style monotheism?
