I'm a Vodun Child

When I stand next to a mountain, I can chop it down with the edge of my hand.  Pick up the pieces and make an island...might even raise a little sand.  I'm a Vodun child.  I did not mean to take all your sweet time.  I'll give it back to you one of these days.  If I don't meet you within this world, I'll see you in the next one...don't be late.  I'm a Vodun child.
