Uruz is the vowel u (as in spoon)
Anglo-Saxon Rune Poem (from ragweedforge.com)
The aurochs is proud and has great horns;
it is a very savage beast and fights with its horns;a great ranger of the moors, it is a creature of mettle.
Uruz translates to auroch, a undomesticated bovine whose ancestors are our cattle. As I believe I indicated before, their horns were greatly prized (to the point that they were imitated after they were extinct in metal, wood and bone) but while they were alive it was a great deed to successfully hunt and kill one.
Esoterically, Uruz symbolizes primal strength, the physical body but also the subtle body strength. In a reading it shows that strength is being accessed, that the potential is being shaped, While the final result may not come into being yet, the process has begun. In my case, the strength is being tapped because I am having two consecutive long days, and I am going to need the power to keep going until I can finally stop, rest and recover.
Uruz is also considered one of the main runes used for healing and health, focusing subtle energies in supporting and maintaining vigor and vitality, which helps in healing and maintaining health.
