The Difference Between Daytime and Nighttime Rites

Jung emphasized that the archetypal self, mercurious, could manifest in a very positive, helpful way or it could be destructive. I think it's very interesting that these ancient rites sort of picked up the difference between those. The ones that were offered at night, you can just really see, this is an attempt to placate the unfriendly powers. Do you have an idea about what's going on there?
