Card II of the Major Arcana
of the Tarot
The High Priestess is a card of thoughtful calculation. The Priestess' power lies not in her ability to exert brute force but in her ability to know when and where to exert that force. The priestess spends most of her time considering, reading, taking in.
The Priestess in a reading often means that the time is right to wait, that energy would be best spent in research rather than in action.
