めいかい - Clarity, The Realm of the Dead

People often mention, in relation to those losing their sanity, moments of "Clarity".
They mention these moments as positives, as signs of improvement, or, if nothing else, moments where mental deterioration isn't so bad.

I find it to be quite the opposite.
How can I have clarity if there is nothing that opposes that clarity?
Things aren't constant. It isn't always the same. My sanity waxes and wanes, it comes and it goes.
It is my rational thought that leads me down the path of anarchy.

If it is rational thought that leads me into irrationality, then what can I do but to go down that darkened path?
