Your gateway to endless inspiration
So I had written this post, promising something similar on Nordic types of magic. I’ll say this to begin with: even though it is my branch, it’s not something I’ve approached academically very often, so purists might catch me saying something not entirely correct, but whatevs.
The standard disclaimer still applies–this is my impression of these terms based on what I’ve read and seen, and aren’t meant to be concrete definitions.
SEIÐR (Proto-Indo-European *h₂seut-, “to move about, roil, seethe” + Proto-Germanic *seuþaną, “to seethe, boil”) is considered a Vanir magic, having been taught to the Æsir by the goddess Freyja. It is worked the majority of the time after utiseta, and involves communication with wights or other spirits. Seiðr is usually worked in an altered state of consciousness (ASC) and primarily utilized for divination, illusory magic, astral travel, or channelling. Practitioners may be called seið-worker, seiðkona (seiðwoman) or seiðmaðr (seiðman).
UTISETA (Old Norse, “sitting out”) is a preparatory practice for seið-workers. Traditionally, the practitioner goes out into a place of the dead and seats themselves upon a burial mound, with the object of task being to come into communion with the spirit that will be worked with during the practice of seiðr.
SPÁ (unknown origin, possibly Proto-Indo-European *spey-, “stick, staff”) is the power of prophesy or foresight, by ‘the determination of ørlög’. Ørlög is ‘the law of fate’ as determined by the Norns. Practitioners may be called spá-worker, spákona, or spámaðr. The term ‘spáwife’ is also commonly used. One who is highly skilled with spá or born with the innate ability may be called a völva, which is a traditionally feminine title, since such magics were seen as being in female domain.
VARÐLÖKKUR (Old Norse “warding songs”) are songs to be sung in preparation for seiðr or spá which are intended to help bring one into ASC. Unlike galdr, varðlökkur can be very melodic, and are today widely inspired by joik and kulning, two traditional singing styles amongst certain Nordic peoples.
GALDR (Proto-Indo-European *ghAl-, “to shout, to sing” + Proto-Germanic *galdrą, “incantation”) is viewed as a more Æsir brand of magic due to its seeming rigidity, but is similar to varðlökkur in the intent to induce ASC. Galdr is often called “runic chanting” and refers to the repetition of the sounds of the runes, i.e., if one meditates upon the rune fehu, then one may continuously gald the sound fe. Practitioners may be called galdra-worker, galdrakona, or galdramaðr.
