Funnily enough, manuscript reading came out to be 3 þurs-maidens of all-mighty Nature, but should be 3 þurs-sons. They are the 3 qualities of Nature: True, Rush, Inert/retarding. Always all 3 together.
We know not that they are so bossy, that they meddle up with all our activity. We know not that they are the rulers of the world.
The only way to get out of their sphere of dominance is to transcend thought and space-time. Þursamegir (þurs-macs (/sons)) are only in Miðgarður – luckily!
Note: manuscript-reading is tricky. Meyjar means maidens (singular nominative mær), megir means sons (macs; singular nom. mögur – Irish mac).
