Look at the link below for pre-research on the upcoming Summer 2009 Advanced Stage Combat Class: Jedi Camp (Lightsaber technique). This website is a folkloric/comparative literature site I always use in my DU classes for many reasons--the author has done her homework and has some really cool Joseph Campbell-esque folkloric traces through film and literature. This page off the website is specific to the lore, inspiration, and symbolism of the lightsaber. Enjoy, and get psyched up for the summer! Details on Jedi Camp to follow closer to summer.
Thanks to this site for the Master Replicas Force FX lightsaber image.
