Dazzling Darkness...

Every now and then,
I'm dazzled by a darkness,
Emerging from its den,
A shifting, inner recess.

It begins with a why,
A nibble at the hale hope;
Till it doesn't imply,
And everything is in its scope.

What does anything mean?
I balk, too tired to tread;
Will it not ever wean,
Off feasting on my dread?

What does draw it out,
Something read, seen, or said?
I merely grope about,
Waiting, once again, to be led.
