Thurisaz is the third rune of the Futhark and of Freya’s Aett. It represents the TH sound for which there is no English letter equivalent. But in phonetics there is the 
(Thorn) symbol for it, which is a mediaeval variant of the rune.
Thorn was also the late Anglo-Saxon name for the rune. In Norse it was called Thurs. The original Norse meaning of the word is “Frost Giant”, and you will find Thurisaz translated as giant, monster, demon or devil reflecting this original meaning.

It’s not uncommon for the rune meaning of Thurisaz to be described as a thorn that is most sharp, a grim and evil thing to take grip on or touch. However, it is representative of Thor and his hammer, protecting Asgard from the thurses, giants who resist the expansion of consciousness throughout the multiverse. In every respect, the energies of Thurisaz are a forceful enemy of unconsciousness, ignorance and the rule of brute violence. Thurisaz represents the warrior that combines consciousness and wisdom with matters requiring force. Thor is the champion god of courageous and free human beings and the ultimate physical fighting force.
Thurisaz is also a fertility rune in the sense that it breaks down the barren and hard, rocky realms into workable soil as to bring fruitfulness to crops and wombs. The best mental state for working with the rune is enthusiasm, rather than anger or fear, as the former will much better sustain right awareness and diminish the potential danger of dealing with strong Thurisaz magic.
T
his early rune is representative of the use of tools and technology (so is KENAZ, to an extent), whether physical or psychological, especially as weapons of protection or active resistance against forces detrimental to the expansion of consciousness and awareness signified by DAGAZ. Human consciousness is a state of mind that evolved from pre-existing state of unconscious which continually strives to re-establish itself. Unless we promote consciousness actively in living out our lives we will succumb to entropy.
The power of Thurisaz is easily located because it is on the borderline, the frontier of consciousness. It is wise to never start a fight, but if one has started, be sure to finish it.
The idea that Thurisaz embodies both destruction and fertility seems paradoxical at first but underscores the cyclical nature of existence itself.
‘Breaking resistance’ resonates well with personal growth narratives prevalent today, emphasizing the need for conscious effort in overcoming barriers.
‘Constructive conflict’ poses a thought-provoking notion; can it indeed lead to positive outcomes if handled with awareness? It raises significant questions.
‘Destructive storms’ as metaphors for inner turmoil seem an apt reflection of contemporary challenges, demonstrating how ancient wisdom remains relevant.
‘Awakening of the will to action’ as mentioned here is quite relevant in today’s context where individuals grapple with inertia in a fast-paced world.
‘Understanding of division and separation’ invokes thoughts on interpersonal relationships and conflicts that are ever-present in modern society. Quite insightful indeed.
The discussion regarding Thurisaz offers an intriguing perspective on how ancient symbols relate to contemporary psychological concepts. It is fascinating yet complex, the interpretation of such runes.
While many might see Thurisaz merely as a rune, its implications on societal constructs should not be understated. The duality of its meaning reflects much about human nature.
I agree with you; the linguistic roots of Thurisaz and its historical contexts provide deep insights into our collective unconscious.
