Thurisaz is the sound “th”
Anglo-Saxon Rune Poem (from ragweedforge.com)
The thorn is exceedingly sharp,
an evil thing for any knight to touch,uncommonly severe on all who sit among them.
Thurisaz, the thorn and the thurse (ice giant) is the rune of misfortunes, challenges and difficulties. It indicates that things are doing to be difficult today, as you will be encountering a lot of things that are unpleasant or just hard to deal with. Perhaps an injury will occur, or a vehicle will break down, or you will miss your bus. Don’t expect today to be an easy day.
