I felt like a moth who got himself too close to the light
Except I didn't burn, I turned cold after that night

from Immortal Technique (Ft. Jean Grae) – You Never Know Lyrics on Rap Genius

A metaphor to compare his situation and feelings to the way a lowly moth will become dazzled by a light bulb and seek to bask in the light not knowing that it will only bring pain.

And after this he didn’t burn like a moth but became cold, in other words very jaded and bitter. Very good metaphor.
