Answer:
Hm..Not sure how to answer this, but I think the quote that states the theme of the story you're reading is, "When the sun rose, I thought, 'My journey has been clean, now I will go home from my journey.'"
Step-by-step explanation:
The other quote I would go with is, "My magic did not help me at all, and yet there was a fire in my bowels, a fire in my mind." However, this particular quote did not make quite enough sense to me; yes, you have fire in your mind and bowels, but why? It just didn't make much sense to me.
The quote, "The Forest People themselves do not come near" quote was just..vague to me. To be completely honest, I was wondering about the Forest People themselves, and what exact thing or place that they wouldn't approach at all.
Lastly, the quote, "If I went to the Place of the Gods, I would surely die, but if I did not go, I could never be at peace with my spirit again," was kind of a statement. I read it a couple of times thinking, 'hm..this could sound like a theme just a bit, if only the sentence didn't sound like a statement the character of the story had made.' Also, to be completely honest, I don't think this quote could state a theme of any kind.
I hope that this helps.
