Yet none could have perform such miracles under observed experiment..
interesting
Nope.
I do however believe that some people have the ability to bring comfort using the ability to "read" others. They manage to bring comfort as they understand what this person needs the most.
I Also think people are easily "bought".
They will believe many things especially if it brings them comfort.
more than that
I Come from a family with a long "Spiritual" abilities.
Myself have an "official Tarrot reader" diploma.
I Can say it is a great tool.
I used to open cards for people and many times got a "wow" response.
I Know today that it is not really spiritual.
It is based on being able to "translate" an image to a person's state of mind.
If i see a very sad in front of me, and would draw a "Death " card...
I can translate this card to fit the person in front of me.
I Could say something like: "I See a very hard period in your life, This card represents the death of this era".
On the other hand, I could just as easily say: "I See you have lost something vary valuable recently, This card represents your loss".
Either way, I Will probably be right.
If you go to a medium as a person to get comfort from, why not? But my suggestion would be not to make decisions based on what a "medium" tells you, rather get what feels right for you and study your actions before taking them.
