The High Priestess represents intuition and the subconscious. She holds in her lap a scroll of secret knowledge, and behind her stand the two pillars symbolizing masculine and feminine, as well as all the dualities in life. In her complete passivity, she is able to bridge this gap. A screen covers the gateway behind her, signifying that the way to higher understanding is yet closed. From her feet spring the origin of the stream of subconscious thought that flows through many other cards in the Major Arcana.
This card shows Hinoto, the Dreamgazer that walks through the shadowy world of dreams, conversing with others only in thought. She knows many things from her dreams, including details about the fate of the world. And often, her dreamscape is on the surface of water, with the reflections showing "shadows" quite different from their upright versions.
