What is the last sentence of "I long for freedom, but I know it well"?

I long for freedom, but I know it well. The last sentence is how the human body can climb out of the dog hole!

The doors that people come in and out are locked,

The hole the dog climbed was open,

A voice shouted:

Climb out and set you free!

I long for freedom,

But I also know-

How can a person's body crawl out of a dog hole!

I can only hope,

That day-

The underground fire is burning,

Burn this living coffin with me,

I deserve eternal life in fire and blood.
