The Moon is one of those great mystery cards in the Major Arcana. In many decks, the imagery includes two hounds, water, towers, at least one moon, and a crustacean. It’s the second of the three celestial Trumps, between the Star and the Sun.
Time For Reflection
Unlike the Star and the Sun, the Moon doesn’t create its own light. Though it shines, all of its light is reflected. Because it can only reflect light cast upon it, the Moon spends much of its time partially occluded. Light represents knowledge. If the light is hidden, so must knowledge be. Because of this, The Moon represents thoughts and ideas that we have hidden within ourselves. The water can indicate that the hidden things are lurking in our unconscious mind.
The two dogs, usually one dark and one light, also symbolize two parts of ourselves. One is the part with which we’re familiar. The other is the darker half, or Shadow, which we must learn to face if we hope to grow as individuals.
Wax On, Wane Off
Different Tarot decks depict the Moon in different phases. In the Alchemical Tarot, the Moon is pictured as waxing, or increasing. However, in the classic Rider-Waite deck, the moon is waning. One shows more light and the other less. Both, however, should remind us that our work at understanding ourselves is cyclical. At times, we feel as if everything is clear, and at times, nothing makes sense. Patience and reflection help us integrate more Light and knowledge when it is available, and help us understand the darkness while we wait for the Light to return.
