Question

Fire overflowing
Rain melting, inside
Gazing upon eternal labyrinth

What's the meaning of this?

Answer 1

The question is a bit difficult, because linguistic information is dependant upon the context of enonciation, especially when it comes to metaphoric discourse. If you were to ask the same question about a seemingly down to earth question ("the sun rises east"), people could answer because they can infer the context from their own knowledge of the world. In the case of litterature for instance, specialists and scholars will often disagree on the meaning of sentences of text.
In the case of the text you suggest, it does not mean much unless you tell us more on the text (even though "gazing upon eternal labyrinth" is maybe more transparent, probably refering to life as an exitless labyrinth. From a first person point of view you can watch a labyrinth all you want, it won't provide any answer to your question unless you actually tread it, which would be a way the author perceives life. Then the endless part would mean that even if you make a choice and discover a new portion of the labyrinth, it does not make you walk out of it, which would be his/her vision of life. Now is it endless ? as life is not… It depends on what is the labyrinth).
Good luck W/ this
