Like fire comes from the poem "Like fire".
The original text is: I want to, like fire, keep burning and burning, until the fire dies, the warmth will still surround me. I want to be like fire, keep burning and burning, and even when it is extinguished, I can set sail in the wind. Let my ashes scatter to every corner of the earth; let my body be buried in the warm embrace of the earth. I want, like fire, to burn everything about me, my breath and my hair, to her. She has black eyes and yellow skin. She is, so beautiful and lovely that I am willing to burn everything I have to express my love for her. Forgive me, I am just a small body, too mediocre; believe me, with such a body, I will work very hard, and I will keep burning, like fire.
