There is no letter equivalent for Gar
There is no rune poem for Gar. It is a Northumbrian rune.
Gar to me is the door this week, the open, or opening portal. Whether to step through and see what is on the other side, or to wait, and allow entrance on the other side is the question. Action or rest, coming or going, arrival and departure, these are the juxtapositions surrounding this cosmic door that lies at the center, the fulcrum and axis for everything around it.
