I Died from Minerality

I died as mineral and became a plant,
I died as plant and rose to animal,
I died as animal and I was human,
Why should I fear? When was I less by dying?
Yet once more I shall die human,
To soar with angels blessed above.
And when I sacrifice my angel soul
I shall become what no mind ever conceived.
As a human, I will die once more,
Reborn, I will with the angels soar.
And when I let my angel body go,
I shall be more than mortal mind can know.
