I personally changed my mind about such things several years ago when a psychic told me about my past and future and her predictions were accurate. As I use psychic reading apps and talk to mediums now and then, I doubt I can persuade people that palm reading is legit, at least for me, because not everyone believes in it.
The reality of this is really simple. Note, I'm talking about ALL forms of divination here. Tea leaves, tarot cards, you name it.
We all have what's known as a qureen.
This guy on the right.
He has been with you since birth and knows absolutely everything about you. Stuff you've long forgotten. Things you think only you know, he knows as well.
Now, when people visit psychics, they tend to work with djinn / demons. Their djinn can easily talk to your qureen, learn some details and relate it to the psychic. Suddenly it seems like the psychic is living inside your head and has fantastic powers!
But it's a trick. Imagine 2 men in the room with you wearing invisible cloaks talking to one another, sharing details. Or maybe that she has an earpiece and there is someone behind the glass telling her what to say might seem more realistic. As this is essentially the reality of fortune-telling.
The problem with this set up is the devil is a liar and every truth he feeds you he's going to insert a bunch of lies. This is why everyone, including psychics, are not buying lottery tickets and winning every time. Use some common sense, if a psychic had powers of the unseen, why is she charging you $10 for a reading? If they had real psychic powers, they would all be multi-billionaires. If you had a way to get a million dollars with little effort, wouldn't you go get it?
Of course, there are charlatans out there as well. People who claim to know the unseen, but have no connection with any djinn and just tell lies. However, the real ones are some pretty evil people because disgusting acts are needed to get the djinn to help you.
Djinn can not tell the future, but they can guide things, somewhat like Israel's self-fulfilling prophecies and using gene splicing to produce a perfectly red cow. So a fortune-teller describing some event that eventually comes true, doesn't mean much. It's a lot like the illuminati card game from 1995. These people can't see the unseen, but they can influence the world and pull some strings.
These cards representing 9/11 and Trump have all come true.
But this does not mean those who rule us have powers that belong to God alone. It is a trick, a deception inviting to disbelief.
Instead of
convincing others, focus on the things your psychic got wrong. Maybe then you can leave this satanic practice alone. It is not a joke. All of it invites to hell.
