I have gotten some good information, and thank those of you who have taken me seriously. While Pon Farr is a biological condition, it is surrounded by ritual, and this is what I will be writing my paper on.
I would love to include more about the actual marriage ceremony, but can't find much and don't think it was ever performed on any of the tv series or in the films, though please correct me if I am wrong. Can anyone tell me what happens at a Vulcan wedding from beginning to end? What do the bride and groom go through to prepare for it, etc?
