After ten years of dealing with problems and troubles, I was at my 
wits' end.  The least of which was terrible headaches that the doctors couldn't help me with.  I was just looking for a solution...ANYTHING.  I truly 
understood why some people were willing to believe in charlatans and 
quacks... when you suffer enough, you will try anything.  Even if that person is wearing a grass skirt and waving a black chicken around his head.
Then,
 by providence... or perhaps by God's Will, a friend told me to try 
reciting the 15 Prayers of St Bridget.  I'd never heard of these prayers
 but I was willing to try.  Then the very first day, things started 
happening around me.  Crazy things.
I called up my friend and demanded to know what sort of prayer was this.  He asked why I would query something good. 
This is what he said :
The St Bridget Prayers uncover malice around you.
The St Bridget Prayers force people to speak truth.
Just those two was enough to upset my life... before it settled it in a different state, changed forever.
When
 I did research, I found out that St Bridget of Sweden was a mystic (but
 then most of the saints were!) and this prayer was a mystical one.
For
 me, the prayer took away old addictions and gave me strength to renew 
my spiritual life.  It has changed my life and my destiny.  Besides taking away my headaches.
And this prayer is the reason I became a Sunday School teacher.  But of course, the real story is a bit more complex than that :)
