The sun and moon are powerful symbols representing opposing yet complementary forces, often embodying duality, balance, and the cyclical nature of life. The sun is typically associated with light, warmth, masculinity, and the cycle of day, while the moon is linked to darkness, coolness, femininity, and the cycle of night and the tides. Together, they can symbolize the harmonious balance of opposing energies and the interconnectedness of different aspects of life.
