I have been mulling over some difficult situations - driving myself a little crazy to the point of insomnia. I decided what was most needed was to withdraw and quiet this busy mind. By sitting and meditating I am able to shield myself from those piercing thoughts. I imagine my aura creating a strong but transparent boundary where I am able to rest and heal. Painting this card was a perfect lesson.
The Four of Swords means take a rest from your challenges.
