proof that some things shine hardest when they're slowly burning down.
means To emit a steady, soft light or heat without flame — or, of a person, to radiate warmth, health, or happiness.
from From Old English 'glowan,' to shine like heated metal or embers. It belongs to a whole luminous family of 'gl-' words in the Germanic tongues — glow, gleam, glimmer, glitter, glint — all clustered around the idea of light, possibly tracing back to a Proto-Germanic root meaning to shine. The 'gl-' beginning seems almost onomatopoeic for brightness, the way the lips part to let light out.
