Everyone has the potential to be Psychic, but not all have the ability to be a Medium.
Good point about certificates.
I have none whatsoever and do not think some things can be taught at all like to be a Medium. There are ways to develop abilities, but you have to have the ability first.
Its like going from kindy to high school then Uni. Some will progress to the highest level and be stronger and even jump ahead in classes whereas others will not go passed high school level....or even kindy if not interested.
But a lot of things factor in.
I would go by word of mouth rather than a certificate - even tv celebrities I am not taken by.
However, I did stumble across an excellent Medium (she was not supposed to be there) down the coast from Ireland in May. The real deal. Quick delivery and details only her sitter could know - even a gravestone that had the wrong spelling!!! Breath of fresh air amongst the mediocre lot that were not such strong Mediums. Hell...others there were not great either that were card readers or Psychic.
Few of us tried different readers and they were "okay", but that is all. $60 for 20 mins. And not the elite of the elite I reckon. Seen better for more and a lot less.
Certificates really are just a front for some I reckon.
As I see it a certificate just says I paid some money, I took a class, and I got a certificate.
A certificate for taking a class does not mean you are a full medium nor does it mean you aren't.
Lets face it spirits are slippery things they don't always cooperate.
They don't appear on command like your puppy...energy has a lot to do with it and timing.
I actually ..well I guess I don't believe it is teachable.
I can't imagine what a class could teach me that spirit hasn't already taught me through the experience of practicing mediumship.
I always see certificates as something that people use to draw in customers...look I'm legit I have a certificate.
The proof is in the pudding....are you getting meaningful messages that people can confirm are from their loved ones....if yes you are doing what you should.
With or without a certificate.
People make such a stew of it...seem to labor over it, I think they really believe spirit won't come through if they don't take a million classes.
I say open your arms wide offer yourself to be of service to spirit to pass messages on from the other side and wait....that's what I did and I've never been so busy with spirits.
I do think what getting a certificate can do is get you in contact with like minded people.
And serve as a jumping off point for other activities...so in that way it is good.
P.S....I worked at a psychic fair for years we had many many readers and mediums come in and out the doors...some fake some real...the fakes didn't last long...people aren't dumb they always gravitated to the real readers and the fakes just kind of faded out when it wasn't worth their time to sit at a table all day with no clients.
