Reason

A lionhead guarding a door.

When we talk of reason, we always also talk about death. For like death, reason always lurks behind every problem, every solution, and every discussion. Like death, reason is cold. Like death, he might drive us to our highest altitudes and deepest pits alike, and down or out again.
It doesn't matter for him if our reality is the reality or merely a construction on top of the reality that is the core of all things (it doesn't matter for him if this core exists, either), for he infects, conquers, every world that blooms up anywhere. Yet he is always a gentle invader, and bows to the rules of each reality he does inflict - and those who blame him for driving them to the gallows, into the war, to loneliness or sin really only blame themselves - the reason they followed was, in this incarnation, only a product of the reality that is themselves

For at the core of being, reason and death are cruel, but just in their emptiness.
