Jera is the letter j, pronounced with a “y” sound.
Anglo-Saxon Rune Poem (from ragweedforge.com)
Summer is a joy to men, when God, the holy King of Heaven,
suffers the earth to bring forth shining fruitsfor rich and poor alike.
Jera, year or summer, is a rune of time. It signifies the fruition one’s labor after a period of patience, and commitment to bringing about the success one seeks. If you are starting a new venture, it will be successful, but it will take effort and patience until it succeeds. IF you are looking at it’s completion, don’t stop, but continue to follow through, in order to build up to your great success
