How to deal with the "clockwise shuffle" and "counterclockwise shuffle" of tarot cards just bought?

Clockwise shuffling is like this-

Tile the back of your tarot card upwards, and then start shuffling the cards clockwise like "playing mahjong", with appropriate gentleness to reduce unnecessary wear and tear on the cards.

How long you shuffle depends on your personal meditation time. If you think you have finished communicating with tarot cards, you can stop shuffling and start cutting cards.

The above is my answer, I hope it will help you.
