Can one person use two sets of tarot cards at the same time?

You can have two tarot cards, as long as you can fully concentrate on divination, and don't confuse the different spiritual fields and feelings of the two cards, resulting in dislocation of strength and confusion of divination results. Then, having two cards is no problem at all.

If there are mistakes in the opening, as long as they are not related to principled mistakes, they can basically be ignored.

If you are not at ease, you can choose to open the card another day.

Tarot cards are old, you should do a card sealing ceremony for them, and then keep your former partner well.

The following is the specific process of the card sealing ceremony-

Seal the tarot card and let it sleep. It won't affect you.

The so-called card sealing does not need to prepare anything. First, look at each card carefully. Then put away the other cards with 22 big aces, arrange the big aces in two rows in order, touch them in order with your hand that often holds the cards, then fold them in order, and then treat the small aces in the same way.

After all the cards are folded, wrap them in a black cloth and tie them tightly with a black rope. You can take them out at home, but you can't use them anymore.

Well, this is the basic ceremony of sealing cards. You can still give it away as long as it appeals to that person, but you can't use it yourself.

After the card sealing ceremony, you can buy another deck of tarot cards and continue divination.

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