Anglo-Saxon Rune Poem (from ragweedforge.com)
The joyous man is dear to his kinsmen;
yet every man is doomed to fail his fellow,since the Lord by his decree will commit the vile carrion to the earth
Mannaz, the rune of Humanity, is an expression of everything human. from the most primal sense to the highest and ideal conception. Our minds, hearts, lineages, social connections, divisions, prejudices, and spiritual essence, are all comprised within the simple, yet complex form of Mannaz.
Mannaz expresses the both internal and external influences within the day. It is internal, because you can control how you react to anything, mastering the personal man, and lettings yourself act from a place of that personal mastery. It is an external rune, because it shows the presence of people coming into your life, and exerting their influence on you. Generally, the influence will be benevolent, even from the most annoying or upsetting of encounters. If you are having problems and find yourself being very upset, or seemingly having a moment that will “ruin” your day, spend some time with Mannaz. Imagine it in your mind, draw it, galdr Mannaz, and allow the forces of this rune to help in aligning you, restoring your center and focus, and possibly clearing the mind so that the right action or response can be perceived by you.
