Reflections from the edge of madness

So here I am once again.
I walk a precipice of a different sort.
I am free, at last.
I cry tears of joy mixed with pain,
Yet I cannot tell which drop is bitter
And which is sweet.
I am the Free Man, and my sins are legion,
But I remain free, no matter what wrongs I have committed.
The call from beyond the borders of light is potent,
Virulent poison that calls me forth into the darkness.
I try to resist the urge to leap headfirst to certain death,
Yet the call is too strong to ignore.
The voice is sweet as honey, temptation
Given form.
Immaculate in dimensions,
Its eyes stare into my soul.
They see me for what I am
As no mortal eyes have ever beheld,
And call me forward, daring me to come to them again.
She is a nymph, temptation incarnate,
The promise of all I desire.
Yet I know that the promises cannot be true.
They are illusions, mere shadows in my dreams,
That shall vanish as smoke through my fingers.
I cannot hold on to water,
Nor can I embrace the air.
Yet somehow I believe that these ethereal dreams are within reach.
Desire is not a facet of logic,
But a creature all its own,
Spawned by chaos and the human soul.
My path is strewn with pebbles, and one false step threatens to o'erwhelm me,
To bring me down.
I fear not the darkness, for in it is a perverse warmth,
Though I know that in the end it shall kill me.
Embrace me, sweet death,
Enfold me in your arms.
I no longer wish to walk this thin line every day.
Whisper into my ear, and promise me lies.
For from these lies, I draw comfort.
I find meaning for all that I am.
And all that I shall ever be.
One more step, let all follow me
And come to dust.
