The concept of duality in mythology originates from the acknowledgment of opposing forces in the universe, such as light and darkness, life and death. Many myths explore these contrasts, reflecting the complexity of existence. For example, in many cultures, gods and goddesses embody both creative and destructive qualities, illustrating that neither aspect can exist without the other. This duality fosters a deeper understanding of balance within the world and provides insight into human experiences, reminding us that life encompasses both joy and sorrow.
