In Daoism (Taoism), mist (and fog) is often used as a metaphor for the Unknown, the Hidden, or Mystery. Mist as a symbol of the hidden forces of nature, the secrets of life, and the elusive nature of the Dao (Tao) itself.
Mist is also associated with Yin, the receptive force in the universe, mist being formless, undefinable, ever changing.
Mist can humble us and invite us to be open to the presence of the Unseen. Mist as a living being, a mysterious teacher, and by being her students, we can cultivate an inner stillness, and walk through the portal between the physical world and the spiritual realm.
