There’s a rune (Nordic oracle system) called Isa, translated into English as stand still. It looks like the capital letter I.
In his Book of Runes, Ralph Blum describes Isa as symbolizing, “the winter of spiritual life.” In other words, a time to stop and do nothing.
He goes on to say, “positive accomplishment is unlikely now. There is a freeze on useful activity, all your plans are on hold… trying to hold on can result in shallowness of feeling… seek to discover what it is you are holding onto that keeps this condition in effect, and let go. Shed, release, cleans away the old. That will bring on the thaw.”
