What magic in Asatru?
You bet ya we have magic but unlike Wicca or Paganism not everyone does magic.Magic is left to those who have the talent and skill.
There are two kinds that are used they are the Sedir and Rune Magic. By the way folks Sedir is one of those words that your going to see half a dozen ways to spell!
A user of magic in ASATRU is often called a Vitki or Vitkia one of there traditional colors is red another being green which is FREYA's color. Either females or males maybe Vitki though you will more often find women as Vitkia.
RUNE MAGIC: ODIN taught us the runes and how to use them so its always wise to consult him before casting. The most common form of Rune Magic is to cast fortunes much as one would Tarot cards. There are many good books on the subject. Also Runes are used when casting various spells.
SEDIR: FREYA gave us this type of magic so once again it is wise to consult with her before casting spells. Sedir is a way of reshaping the inner or outer world with the will of the Vitki. Sedir makes use of magical materials and substances.
And yes folks I am being skimpy on the information as the use of magic is not for everyone as it will bite you back when you cast spells. So if you truly whish to learn find yourself a teacher and learn from them.
A third kind is the natual healer who is usaly also a Sedir magic user though not always.
