Repeating my phrase

I exist, I was Human, find another body to live in.
I exist, I was Human, find another body to live in.
This is the phrase I need to remember to repeatedly say,
this will be repeated until the next body comes my way.
When this one ends I'll be sent to darkness's light,
repeating that phrase until I have new eyes for sight.
What will you do,
when the end comes to play?
What is your view?
What will you repeatedly say?
