The idea of duality is prominent in mythological characters, often evident in figures embodying conflicting traits or forces. For instance, the trickster is both a creator and a destroyer, highlighting the complexities of human nature. Characters like Shiva in Hindu mythology represent both destruction and regeneration, illustrating the balance between good and evil. Duality manifests in narratives through moral quandaries and the blending of contrasting traits, underscoring the belief that life encompasses both light and shadow in its essence.
