Need is oppressive to the heart;
yet often it proves a source of help and salvationto the children of men, to everyone who heeds it betimes
Nauthiz or Nyth translates as Need. As the rune poem shows, it is a difficult rune, but can also bring great benefit if heeded in time. Often this rune is connected the powers that govern fate, expressed in the Northern tradition as the Norns, but they can also be known as the Wyrd Sisters.
While other runes also can relate to those mysterious forces which seem to shape the lives of men and gods, often known as Fate, Destiny, Chance and of course Free Will, Of those runes Nauthiz belongs with Fate and Destiny. As its name literally means Need, it points to those things that Need to be. Sometimes that needed event is easy and pleasurable, other times it can be challenging and painful. Both can bring their own lessons and shape people for good or ill.
However, the writ of Need is large, and not all things fall under its purvey. To blame everything on Fate is not what is meant or needed, as often times those fated things are acted upon, even without even realizing it.
