The rune is a simple arrow pointing up. It signals the spiritual warrior, the energy of such a warrior. Thus did it become, in my mind, the warrior self. In this sense, we are all spiritual warriors. We all do battle with the self.
The hardest fight is with the self. Overcoming your impulses and your own doubt is the only challenge that really matters. Wrestling with God is easy by comparison. There is nothing anyone can do to you, not even God, that can be more hurtful than what you can do to yourself. You know your biggest fears, your deepest doubts, more thoroughly than anyone else does. You know them from the inside and can use them against yourself in ways others cannot even fathom.
It is a solitary struggle. Try as hard as you might, you cannot escape yourself. And all the help others offer can do nothing about the nagging worry your inner self can bring to bear in opposition to you. At 3 AM you have no one else to help you fight for yourself.
Even if you win, the challenge is always waiting in the wings to be rejoined. Every setback risks an “I told you so.” And yet, without the fight, without the willingness to wrestle with the self, what is left? What else would we have?
Life is about pushing forward, about bringing something from nothing. We begin as nothing and struggle to make something. It is against the self that we must work. Though we fail, it may be enough to know that at least we did not give up.
