Logical Riddle - Flash On A Verge

Life lasts like an instant
When you're on a verge
Illumination of spirit comes, eyes see truth
Actions, thoughts and words
All you've got in your life
You understand that almost all was wrong

You're cause and effect.
And you made a choice.
Every second, and every moment.
Your life was in your hands
Now you can't change yourself
Just pain ahead, the flash on a verge
The future is unknown
And you're ashamed by past
Fear and despair, anger and rage. You cry
Errors of mind and heart
They will to get back
But why must you die to understand?

You're cause and effect.
And you made a choice.
Every second, and every moment.
If life will be in your hands
Think above actions
Which were prompted by the flash on a verge
