What can destroy us?

What can destroy us?
Can flame or smoke
Burn and choke
Or can we hold fast to the rope?
We would like to know.

But you cannot ruin what cannot perish
You cannot destroy that which is omnipotent
You cannot erase what is set in stone,
and cast in iron
You cannot subdue that which is all powerful
You cannot wound what heals itself for what grows in its place will be twice as strong

Save me your pity and your pride
I am indestructible
Because I choose to be.
