Khalk is the letter k
There is no rune poem for khalk. It is a Northumbrian Rune.
Khalk reversed signifies that our hopes, our dreams, our desires, are poured out, spilled upon the ground. Maybe we realize something is just unattainable, in our current situation, or part of it has been grasped, and now is the time to move on to something else, because we realize that we don’t desire it any longer.
Alternately, we can be lost in our dreams and desires, just having them, but failing to act upon them or pursue them. We might instead look to fill ourselves with other things, because we are not pursuing what we really need. Addiction, distractions, anything to escape from the aching hunger of our desires, which terrify us, because they seem so vast and unachievable.
