I'm on a quest to learn about this order, as a client (is that what they're called???) belongs to this and can't be buried till three days after death. I didn't find information about that, but did find a ton of other interesting stuff.
The Rosicrucian Order, AMORC, is known internationally by its traditional and authentic title, the Ancient Mystical Order Rosae Crucis. Rosae Crucis from the Latin means "of the Rosy Cross". There is no religious connotation associated with this symbol; the Rosy Cross symbol predates Christianity. The cross symbolically represents the human body and the rose represents the individual's unfolding consciousness.
