In Celtic beliefs, faeries and other magical beings symbolize the mysteries of nature and the interconnectedness of the human and spiritual realms. They often embody the unknown and can represent both benevolent and malevolent forces. Faeries may guide, protect, or punish humans, reflecting the duality of existence. Their role emphasizes the importance of balance between the seen and unseen. Faeries also serve as intermediaries, reminding humans to respect and care for the natural world. Thus, they symbolize deeper moral lessons and connections within the Celtic worldview.
