What does Berkana mean?

Berkana is an ancient Norse word for birch tree, and symbolically stands as the Norse rune for growth and rebirth. As described in The Book of Runes by Ralph Blum, Berkana “denotes a form of fertility that fosters growth both symbolically and actually. It is the rune that leads to blossoming and ripening. Berkana is concerned with the flow of beings into their new forms. Its action is gentle, penetrating and pervasive.” In order to promote blossoming, Berkana requires the qualities of modesty, patience, fairness and generosity.
