Must tarot cards be sealed with pure black cloth?

Sealing a card is not demonization, but a psychological hint to oneself. It doesn't matter what kind of cloth you use. The point is not what kind of goods you use to seal the card, but whether you seal the card in your heart. Don't believe in divination, and then you don't need to believe in divination. This process is like reading more and reading less. Receiving cards means that you will get rid of the "type" of tarot cards, understand its "spirit" better, and reach the state of "knowing destiny without confusion" This doesn't mean that you can predict the future. This is sheer nonsense. It's just that fear, happiness and extreme peace can be ignored in spiritual cultivation. By the same token, as long as you can see through other people's problems, you can give correct opinions without divination. The function of tarot cards is to find clues to problems. If you can do it yourself, close the card.

However, if you can't do it yourself and are just "tired of playing", I don't recommend you to check the level. This kind of thing is enough once in a lifetime.
