A psychic told me that she doesnt read tarot up-side-down at all just because tarot was not originally designed to read up-side-down. Although no one knows exactly the original root of tarot, but the cards were not invented to read up-side-down.
I then did the research on this, but found out nothing to prove her, and nothing to disprove her. All the sources that I found on tarot, they dont say anything about tarot was also invented to read up-side-down.
But how come some people read reverals on some decks like the Raider Waite Smith deck ? and some decks are not designed to read reversal at all like the Thoth deck.
So, anyone has any knowledges about this. Please share.
