From the Out of Hand Tarot, the Moon; from the Seashells Playing Cards, the American Stiff Pen:
A hand holds a mirror that shows another hand holding the moon. What is real and what is illusion? Our minds have tripwires for anything in the present that even slightly resembles something or someone from our past. Once those wires have been triggered, our mind doesn't bother to register all the facts in front of us, it just fills in the blanks from our old memories. Strong emotions - good or bad - are often a hint that we are relying on unconscious information. The American Siff Pen anchors itself to the sandy seabed using a bundle of silky fibers called a byssus. This clam also can heal small holes or breaks in its shell. It suggests we ground ourselves while curiously examining what is factual and what is pure assumption. Then we can repair these 'holes' with the evidence we find.
