Berkana is the letter B
Anglo-Saxon Rune Poem (from ragweedforge.com)
The birch bears no fruit; yet without seed it brings forth suckers,
for it is generated from its leaves.Splendid are its branches and gloriously adornedits lofty crown which reaches to the skies
Berkana is the rune of nurturing, growth, feminine power and healing. Generally it indicates that there is slow and steady effort to gently build and uplift, nurturing yourself, others, or events, so that things turn in your favor. It is a powerful feminine, but not in a passive way, because it can be strong and seemingly fierce at times, like a mother protecting her children. For that reason, I often see this rune as a queer rune, the rune of Women who Love Women. It is also a rune that aids in birthing, both literal and metaphorical. As a rune of healing, it helps to build what ever is broken or depleted, and often times it will come back stronger then what it was, sometimes even from the most barren and wasted or broken parts. By turning it on oneself, you can access those parts that need the most nurturing and care, feeding them so they grow and thrive.
