In both Eastern and Western mythologies, the concept of duality manifests through the balance of opposing forces, such as yin and yang in Eastern thought and light versus darkness in Western narratives. Eastern mythologies often emphasize harmony and the interdependence of opposing elements for a balanced universe, while Western tales frequently frame duality in a conflictual context. This duality influences cultural values and philosophical perspectives, guiding individuals in understanding their experiences and the nature of existence. Ultimately, these myths reflect the complexities of life and the coexistence of contrasting forces within every society.
