The Nine Worlds
The cosmology of the Norse mythology was composed of Nine Worlds growing on a single World Tree called Yggdrasil. The Nine Worlds were:
1. Asgard, the divine world of the Aesir
2. Alf-heim, the World of the Light and Beautiful Elves and Spirits
3. Nifl-Heim, the world of cold and darkness in the north
4. Jotun-heim, the world of the giants which is in the east
5. Midgard, which is the middle earth of humans in the middle place of the World Tree
6. Vana-heim, the world of the Vanes in the west
7. Muspells-heim, the world of fire which is established in the south
8. Svart-alfa-heim, the world of the dark elves, which is under the Earth
9. Hel-heim, the death world at the lowest point in the multiverse.
Usually the other worlds beside Midgard are invisible to mortal man, but during initiation, the priests liberate the soul of the initiate and he or she is able to walk freely in these other worlds among their various inhabitants.
The Teutonic pagans' myriad gods of nature who manifested as geometric forces composed of inforlation, rather than a singular deific form, influenced the cosmology of nine worlds in the Odinic mysteries. This is very similar to initiation in the Eleusian mysteries of Greece in which the initiate is brought through nine planes of existence comprising reality.
The Norse adept simulated Odin and figures such as Gandalf, the Vikti and Wizard from the poetic Eddas. The adept in Norse culture was called Gobbi meaning High Priest and would serve as an intermediary of the Aesir. Bards were masters of the oral tradition, reciting the Eddas of the gods and warriors of the past. The Drottars or Druids were special elder priests who would have been Gobbi for many years. The Vikti was the Rune-magician; an adept who would use Odin as his primary example and could wield power with the use of runes. The Nordic Wizard was a composite master of all these principles of adeptship and would be considered to be an emanation, like avatars in Hinduism, of one of the Aesir. In the Eddas, Gandalf is recognized as a wizardly emanation of Odin and All Father.
