It's a sri yantra: 49 triangles, two opposing forces that make momentum. My life might get difficult, but I feel like I'm made of perpetual motion, like a stormy sea. And I like to think that the ocean and my soul can't be tamed.
I really like this and think it would be a sick tattoo on the inner wrist. The word valknut is a neologism: it is formed in modern times through combination of ON valr, ‘the dead’ or ‘the slain’ and knut, ‘knot’.
