The word 光明 is formed through the direct, conceptual combination of two independent pictographic characters. The first character, 光, originally depicted a flame (火) atop a kneeling person (儿 in ancient form), representing the radiating quality of light. The second, 明, is a classic compound ideograph combining the symbols for the sun (日) and the moon (月), two primal sources of illumination. When placed together, they create a powerful, layered metaphor where the tangible light of the sun and moon merges with the abstract qualities of brightness and clarity, forming a holistic concept of brilliant illumination that is both physical and moral in nature.
