Hagalaz is the letter H
Anglo-Saxon Rune Poem (from ragweedforge.com)
Hail is the whitest of grain;
it is whirled from the vault of heavenand is tossed about by gusts of windand then it melts into water
Hagalaz comes in with storm and stress, tearing you and perhaps your life apart. Sometimes it enters literally, usually figuratively, as something induces a disruption to the flow of life. It might be the nagging customer who keeps calling and calling and calling etc… or the coworker who just can’t seem to anything right today, and so you are constantly correcting their mistakes, while your work gets backed up. It could also be the cold that sweeps out of nowhere, with just a minor warning, throwing all of your plans off kilter.
