Great messages as always.
Nothing to do with nothing, I was so excited when I saw your title, only to be let down for purely personal reasons. The mark of Cain is a topic very dear to me that I have written about a few times because I have the mark of Cain. Not the mark as most interpret the biblical story but rather the mark as discussed by Hermann Hesse in his short novel, Demian.
“We who bore the mark might well be considered by the rest of the world as strange, even as insane and dangerous. We had awoken, or were awakening, and we were striving for an ever perfect state of wakefulness, whereas the ambition and quest for happiness of the others consisted of linking their opinions, ideals, and duties, their life and happiness, ever more closely with those of the herd. They, too, strove; they, too showed signs of strength and greatness. But as we saw it, whereas we marked men represented Nature's determination to create something new, individual, and forward-looking, the others lived in the determination to stay the same. For them mankind--which they loved as much as we did--was a fully formed entity that had to be preserved and protected. For us mankind was a distant future toward which we were all journeying, whose aspect no one knew, whose laws weren't written down anywhere.”
"We who bore the mark, felt no anxiety about the shape the future was to take. All of these faiths and teachings seemed to us already dead and useless. The only duty and destiny we acknowledged was that each one of us should become so completely himself, so utterly faithful to the active seed which nature planted within him, that in living out its growth he could be surprised by nothing unknown to come."
I have written about the synchronicities that helped me discover that I have the mark, supernaturally placed upon my body sometime in my pre-teen years, and what it means to me, a few times. Here is one: https://medium.com/know-thyself-heal-thyself/my-mark-of-cain-de5db04c5249
I would love to hear from any others who believe they have the mark. So far I have only encountered two others--my channeler Ane and Rebecca Romanelli. I have suspected that a couple others I have met on Medium have it but while they identify with how Hesse decribe it, they cannot locate any similar and unexplained marks on their bodies.
