According to Hindu mythology, Swastika is the sign of prosperity. It wasn't their fault that it came to represent Nazism and thus a kind of evil. And so Hindus have launched a campaign to reclaim the swastika from its Nazi past and reinstate the 5,000-year-old emblem as a symbol of good luck.
Marketing is important, even to religions and schools of thought. But in this case they have a pretty difficult way to go. I'm not sure I could be convinced that this is a symbol of luck and/or prosperity. I don't mind if the Hindus use it differently, but I don't expect them to change our culture's notion of what it is.
All of which is very strange, when you think about it; it's just a symbol, just a mark, just a set of lines. Or is it?
