Isa is one of the most interesting runes of Scandinavian runology.
It depicts an inverted I or pillar, which symbolizes blockage or restriction. Isa turns upside down to show that something is standing in the way, blocking your path.
However, Isa can also have a positive meaning. In some cases, this may be a sign of a break for reflection and rethinking. The Isa rune encourages you to slow down, stop and accept your surroundings. She tells you that acting too quickly can lead to mistakes and bad decisions.
