In case you are doing number of Tarot Card Readings one after the other then it is better to clear your cards after a reading for the next reading. This can be done in the following steps :-
A. You should put your cards ie deck in a single face down pile.
B. Put your hands over the Deck , Palms down (Crossed at the wrists)
C. Then you should separate your hands with a force
This method of clearing your cards will refresh your cards for the next reading.
