Glow, a term encompassing both physical radiance and metaphorical illumination, has been explored by diverse authors as a symbol of transcendence, emotion, and spiritual awakening. From Zane Grey’s depiction of a “glorious light” elevating the human spirit to Phillis Wheatley’s vision of a “heavenly transport glow,” the theme bridges the tangible and the abstract.
Robert W. Service contrasts earthly ashes with “glorious” vitality, while Marie Corelli evokes “burning glow” as a marker of earthly beauty. These varied portrayals underscore glow’s dual role as both a sensory phenomenon and a metaphor for inner light, intertwining it with related themes of brightness, flame, and spiritual resonance.
