Yearning to Fall

What is that strange light in the end?
Luring you in like a moth to a flame?
Filled with tantalising promises 
Promises of glory, brilliance and fantasy

And yet something sane holds you back
Keeps you from burning up like Icarus
Side to side oscillating like a pendulum
You are forever left standing on that ledge

It's that spark slyly reflected back to you in the mirror
It's those dreams calling out to you mid-sleep
It's those emotions rearing for you to take leaps of faith
It's that understanding that you are leading only a half life

So would you go fulfill this crazy urge?
Would you dare to take that adventurous trip into the unknown?
Or do you keep it locked in?
Forever looking down into the abyss, yearning to fall in?
